Flexible gas liner hoses. Choose a gas hose for connecting a gas stove or boiler. Some specific characteristics

The bellows liner for gas is one of three types of flexible sleeves for connecting with gas devices that have replaced the steel pipe. Movable flexible hoses also include rubber-fabric and reinforced hoses, which, unlike steel pipe, have become not only easier to install, but also allowed to move gas appliances in the kitchen room for cleaning or repair.

Sylphonic hose is of stainless steel Used to connect a gas boiler or column. It is also possible to connect and connect the gas stove with it, but when using special.

I suggest detail to consider the advantages and disadvantages, material manufacturing and application, reliable manufacturers, as well as the features of connecting the flexible bellows hose to the gas boiler, column or.

Features of the use of bitter hoses for gas

All currently used flexible hoses are made of different materialshave different specifications and operational service life, but at the same time they have common positive qualities:

- Easy when installing;
- ease when installing;
- Convenience when operating.

Types of bellows hose for gas

Sylphonic gas hose is recognized as the most comfortable and safe of all kinds of flexible hoses. This gas supply stainless steel and polymers with corrugated is made. top layer. Due to the fact that there are wires in the material, the hoses can withstand high pressure (up to 6 atmospheres).

Silphon hoses for gas possess the property to maintain their elasticity and initial strength, despite the fact that they are constantly compressed or pulled out in length. To connect K. gas equipment In the bellows hoses use a fitting or a nut with a carving made from brass.
There are several types of bellows hoses:

- Simple having round cross section;
- hoses protected by metal sleeves;
- Polymer coating hoses;
- upgraded hose with valve, triggered for overlapping gas (with raising temperature to high values).

How to choose the right gas beam liner for a boiler or column

What needs to be paid attention to when buying a hose? The most important condition is not mistaken when buying is a visit to a specialized store, where competent consultants will help you choose a high quality product, and not cheap Chinese fake.

Any gas equipment in the house or apartment is a subject of special risk. Incorrectly selected can lead to miscellaneous situations, Up to the explosion.

The first thing you should clarify the seller is the type of hose connection. Immediately throw off the option where the corrugation is glued to the hose, this kind of product will not last for a long time. The housing of the hose must be either welded or solid.

Connecting a gas boiler with a flexible bending hose 3/4 '

Any bellows apply has at the ends threaded connection To connect to gas devices. These compounds differ in the thread diameter and are:

- ⌀ 15 mm or 1/2 ';
- ⌀ 20 mm or 3/4 ';
- ⌀ 25 mm or 1 ';
- ⌀ 32 mm or 1/4 '.

As a rule, wall and outdoor gas boilers For its part, they have a threaded fitting with a diameter of 1/2 'or 3/4'. Therefore, the calf hose must be selected the same diameter as the gas fitting on the boiler or the gas column.

For example, for wall gas boilers "or" "3/4 'with a diameter of 3/4' is needed, and the" CONDI2 "or" Mimax "gas boiler is suitable for the 1/2 'diameter.

Silphon stainless steel stainless steel "Nut-fitting"

In addition, there is an internal or outdoor thread at the ends of the hose. Gas lining can be two types of joined threads:

- "Nut-nut" (both internal threads);
- "Nut-fitting" (one end with the inner, the other with outdoor thread).

Therefore, picking up the hose, you need to know what carving on the gas device and what gas pipe (Crane). If the diameters are different, it is solved by buying a threaded adapter, for example,.

Manufacturers and prices

Sylphon hoses for gas in our market are presented by such famous brandslike "Hudrosta", "Lavita", "Emeflex", "Beka" and others. But now, in connection with the increasing rate of foreign currency, we are looking for analogues of this products manufactured by domestic firms and well-proven themselves in our market.

Such firms refers primarily to the "Tuboflex" campaign, producing bellows for gas at the Uglich plant of polymers. Consider several examples of different lengths, the method of connecting and price.

Tuboflex bellows

Sylphonic hose for gas "Tuboflex IP 100668" is suitable for both gas stoves, boilers, columns, and for other equipment with a gas supply system. This hose has a flexible construction, a long operational period. Made of stainless steel, equipped with mechanical damage protection. The length of the hose 2 meters, half the thread of the half-huma nuts, the weight of 310 g, the method of connection "Nut-nut", dimensions of 240x330x35 mm. Price 667 p apiece.

Benefits of bellows of aircraft hoses:

- reliability;
- safety;
- flexibility of the structure;
- sufficient density;
- the ability to withstand temperatures from - 50 to + 280 ° C;
- the ability to withstand high pressure;
- the ability to pull in length 2 times;
- the ability to connect to any gas device;
— long term operation.

Disadvantages of the bellows liner for gas:

- formation on the surface with the time of microcrack;
- Need to install dielectric coupling When connected gas stove with electric trait;
- High price compared to other types of hoses.

As for the work and installation on the combination of flexible bellows hose with gas boiler Or column, then only a professional should do it. Therefore, we do not give any recommendations to those who believe that any master can easily cope with this. Any gas equipment must connect a specialist permission to this species work. And here it does not matter what type of hose will be used: Sylphonic or oxygen. We watch the video.

To connect plates, boilers, water heaters, furnaces and other household appliances that operate on gas, gas liners are used. They connect directly to the instrument with the gas pipeline, high demands are presented to them. Therefore, the selection of wiring needs to pay due attention.

What to pay attention to?

Wiring allows you to combine gas pipeline and household equipment operating on gas, without welding. This method of connection is convenient and practical. Thanks to the flexible hose, the possibility of moving the devices is facilitated by accessing the stove or for it. Also, the use of such a compound greatly simplifies mounting work. The main requirements are the strength of the equipment. Therefore, today is most often used by the bellows flexible gas liner. It is a corrugated hose that is easily beaten, at the same time durable and immune to external influences. With its bend, the inner section is not disturbed and does not decrease, which guarantees safe work. Durable flexible material and reliable compounds provide good tightness, withstand working pressure, due to which such equipment can be used not only in domestic, but also in industrial devices.

Advantages of equipment

Silphon gas liners 1, 2 choose due to a number of advantages:

• they are flexible and resistant to breakdowns,
• withstand high temperatures
• do not deform
• have a long service life
• provide excellent pressure tightness.

Due to the high quality of materials, flexible products 1, 2 serve as reliably and much longer than ordinary hoses for plates, so they completely pay off.

Not so long ago, the owners did not even have the question of which hose for the gas stove to choose. In Soviet times, these household appliances tightly attached steel pipes to the gas pipeline. It was simple, reliably, safely, but uncomfortable: the slab could not be moved after mounting any millimeter. With the advent of the new product, it was possible to attach the stove with a flexible hose, so that the device can, if necessary, can be rearranged or temporarily move.

Hello, friends!

Never use gas hoses without the availability of appropriate marking, the permission of Russia's Rostechnadzor to their application, as well as certificates of conformity of SNiP and GOST. It is necessary for the presence of a passport of a flexible liner, which indicates the date of manufacture, service life and replacement of the hose.

It is advisable to learn in advance in the gas company of your city about the technical conditions for the methods of connecting gas plates. This may relate to the maximum length of the eyeliner, the method of its fastening and materials from which it should be made.

Requirements for gas hoses

1. Flexible eyeliner is a holistic product, any compounds (couplings, extension cords) are not allowed. One can not do from two hoses.
2. The hose must be resistant to oil and not subject to corrosion.
3. The compliance of the hose parameters of the gas used is mandatory.
4. Access must be provided with a flexible eyeliner (it is impossible to place it in the box, shoes, etc.).
5. Use hoses with a service life of at least 10 years.

The maximum allowable laying length is indicated by the manufacturer of the gas stove. For example, the European Standard: EN14800: 2003 - two meters. The maximum length of the certified gas hose is 7 meters.

In GOST there is no direct instructions in size!

What length are gas hoses?

The most common sizes are the following (in centimeters):

Types of hose

Today, a few varieties of hoses are used to connect the gas stove:

• oxygen;
• rubberotable;
• rubber reinforced;
• rubber with metal braid;
• reinforced from PVC;
• sylphonic.

It is worth considering them more before choosing a lot.

Oxygen

Oxygen hoses were often used in Soviet times, as there were simply no other connection options through a flexible liner. Now this product is moving into the background. Cost - from 60 rubles per meter of the mandon without tips.

Positive traits:

• ability to withstand high pressure (up to 20 atmospheres);
• easy installation;
• cheapness;
• does not carry out electricity;
• you can pick up for any diameter of pipes.

Otherwise - a good option For having his advantages:

• high level of electrical insulation;
• wide range (easy to find for any pipes);
• due to the softness, it cuts into the existing conditions without effort.

You can install the product yourself, but it is better to contact a specialist.

With metal braid

It has an optimal price ratio, quality and durability. Price from 140 rubles for 60 cm finished product. The hose is made of vulcanized rubber and reed textile thread. The outer part is a metal braid.

The gas hose is similar to a plumbing (for toilet bowl, cranes, soul). You can distinguish it on labeling: Plumbing products have blue and red tags for cold and hot waterThe yellow thread is woven into the gas braid.

One of the most common options whose popularity is associated with many positive qualities, including:

• high level of reliability;
• ease of installation;
• a longer service life compared with rubber products;
• large selection of lengths and diameters;
• the permissible temperature has a wide range from -35 to + 50 degrees;
• unpretentious in operation.

Do not use the product without installing a dielectric insert!

Master Universal, since 2003 I have been repairing and finishing the premises, more than 100 completed objects. I appreciate the quality more than the quantity!

Gas services often recommend changing old hoses with metal braid due to the impossibility of checking the state of rubber under braid. If it is impossible to confirm the relevance of the term of use of the product using the passport, then I recommend to replace the eyelid on the bellows or on the reinforced PVC.

Reinforced from PVC

Gas supply from PVC is one of the latest developments. It does not conduct electricity, it is not destroyed as rubber, and almost as durable as a bellows hose. It has 2 layers: internal black PVC, and an outer shell of yellow PVC. Due to novelty, not all gas services are commissioned, so it is better to consult in advance in an authorized organization. Price for 60 cm of the product - from 140 rubles.

Properties of reinforced PVC hoses:

• thoroughly;
• dielectric;
• withstands the touch of contact with a hot slab;
• sufficiently cheap with a comparable service life;
• resistant to oily fog;
• operated under conditions of increased loads;
• complies with the requirements of GOST R 52209-2004, GOST12.2.063-81, GOST12.2.003-91;
• warranty service life - 12 years, real service life - more than 20 years;
• length from 60 cm to 5 m.

The calf hose is made of stainless steel, top with PVC coating. This ensures that he will last for a long time: middle time operation is 25-30 years. Metal braid reliably protects against mechanical effects, and polyvinyl chloride coating provides electrical insulating and resistance to chemicals. Thanks to the corrugated surface, the product is easily bent.

Silphon gas hose It has the following advantages:

• can be connected to any gas equipment: plates, boilers, etc.;
• it has connecting dimensions 1/2 ", 3/4", 1 ";
• has excellent flexibility;
• withstands pressure up to 6 atmospheres;
• a wide range of operating temperatures: from -50 to +250 degrees (installation on the street is allowed, when contacting with hot surfaces, nothing happens);
• able to withstand mechanical loads, aggressive impact ambient, household chemicals;
• hoses comply with the requirements of GOST R 52209-2004, GOST12.2.063-81, GOST12.2.003-91;
• warranty service life - up to 15 years;
• service life - up to 30 years;
• it is capable of ensuring the tightness of the system, even with extreme loads, for example, with an earthquake.

The length of the bellows hose varies depending on the manufacturer.

The "Emiflex" sawing can increase in the amount of 2 times and has the following parameters (in meters):

• from 0.26 to 0.52;
• from 0.5 to 1.0;
• from 0.75 to 1.5;
• from 1.0 to 2.0.

And the firm hoses of ELITELINE have a fixed length (in meters):

The only thing that can scare the buyer is the price. But taking into account his durability, it is the most profitable acquisition.

Do not use the hose without installing a dielectric insert!

Gas Hose Selection Rules

Some simple Soviets Will help choose a gas hose, save time and money and avoid trouble with energy leakage:

• Buy any products only in specialized stores, while do not forget to ask the seller quality certificate.
• It is impossible to acquire Chinese hoses: they are thin and quickly come into disrepair. Also meets a lot of fakes.
• The plates connect only by those sleeves on which a special yellow label is. You can not replace them on plumbing. The latter are not intended for such loads and wears over a few weeks.
• When buying, the eyeliner needs to be carefully examined for damage.
• Separate the size so that the product resulted, and not stretched.
• Pay attention to the attachment methods - the fitting or nut, - pick them in size.

When installing the hose you need to use the following recommendations:

• The sleeve should be laid in an easily accessible place. Hold it into the wall or under the floor is unsafe.
• The bending radius should not be less than its three-time diameter.
• The product can not be stretched, twisted, extinguish, and also paint.
• Metal parts should be protected from condensate leading to the oxidation of the material.
• It is impossible to connect steel elements (tips) with copper, it is fraught with electrolytic damage to the product. Permissible combinations - steel with steel, brass with copper.
• Tighten all connections need tight, but without excessive effort not to damage the thread.
• A dielectric insert is established between the crane and gas sleeves, which prevents the accumulation of wandering currents, which can lead to overheating braid, damage to the instrument, melting of rubber.

Gas supply service life

After installing the hose, you must specify the duration of its service life and remember the installation date. The product, depending on the species, is calculated for a period of 5 to 15 years. It is important not to forget to replace it in time.

The guaranteed service time is listed in the product passport and in the certificate of conformity.

• rubber hoses (with shell and without) - warranty 5 years, service life up to 10 years;
• pVC liner - 12 years warranty, serves up to 20 years;
• sylphon gas hose - 15 years warranty, does not require replacement up to 30 years.

What gas hose is better?

1. According to the ratio of technical characteristics and cost, the leader is a bellum gas hose, not in vain it is recommended by the gases themselves. Do not forget to establish a dielectric insert with this product!
2. Next comes gas sleeve from PVC, it is less durable, but does not require electrical protection, it does not destroy from oil.
What hose for the gas stove you chose?

The gas hose seemingly what kind of simpler product may be a mystery? Came to any economic store, took and forth on the cashier. However, you never thought, what is the difference between the gas hose for the gas stove and the gas hose for?

And the most important thing is that on the shelves of large trading networks such as, Lerua Merlen or Maxid, this product is simply represented in a huge assortment. Injury the question arises: what gas hose is better to buy? On one tray lies gas hose PVC The reinforced polyester thread, on the other, the gas hose of the bellows type, and even lower the rubber sleeve at all and how is it not to get confused?

More recently, literally a couple of dozen years ago, you would not care about how to attach the gas stove. All gas household appliances, after the purchase of "tight" and securely joined us as a rule, the master of their nearest hide with the help of a steel pipe. Of course, about aesthetics or design did not even have thought. There was only one task - rather start using a new device.

Accession steel pipe Correspondingly has several advantages. Such requirements as durability, reliability, security is secured 100%. That's just there is a small inconvenience, wash the gesture under the stove most likely will not get the next twenty years. AND kitchen furniture can't find desired sizeSo it remains 20 centimeters from each side of the slab, but it is not possible to move it. Finally, this kind of problem went into the past, and there is no deficiency for a long time on the domestic economic market, and the flexible gas supply is offered in a large range.

Selecting the gas hose for the stove, or the boiler - a very serious step. From his strength, reliability and safety depend on the lives of many people. Often the result of the illiterate connection of the slab or the gas column to communications becomes an explosion. For flexible appliances natural Gas Exceptionally special, gas hoses are used. Watering use for this purpose is categorically prohibited.

Of course it is better to call the wizard that will provide a professional connection and will give a guarantee. Each of us saw in the news, which leads the explosions of household gas, including as a result of unqualified household connections gas devices. We have known since childhood that it is impossible to joke with gas. However, the modern gas hose allows you to connect yourself. Adhering to elementary safety rules, a similar procedure is able to perform any adult man.

So, go to the store. Let's see what the seller offers, what flexible gas hose to choose and buy for a gas stove? It is distinguished by three main types of gas hoses used in everyday life:

• - rubberotable;
• - rubber reinforced;
• - Sylphon.

Gas hose rubber.

The milded of all types of hoses - rubber sleeves reinforced by textile thread. They have long won the reputation of an unpretentious compound, and are often found in the farm of the maternity house owner. Simple installation work, inexpensive cost, flexible properties and functionality of attractive qualities that determine popularity. On the shelves there will always be available options with different length and diameter.

Rubber - one of best Materials dielectrics. They are used to feed household appliances liquefied gas From gas cylinders and are used in cottages and in private houses. This method of flexible gas liner is the easiest and cheap, but also most dangerous.

A large minus is that with time in rubber, cracks are formed, leading to gas leakage. The only place where it is permissible to use this type of flexible lining - gas cylinders in the private sector. Among other things, the products do not get the necessary stiffness.

It is not recommended to use rubber-free sleeves for more than two years, but in practice they are operated much longer.However, modern rubber hoses are manufactured with inclusion in the composition of elasticcomponents which allow you to use the product up to 5 years.

Gas hose reinforced.

Rubber reinforced sleeves are most common, externally resembling hoses for water lining. Outside, they are braided with steel threads. Although they are called rubber, inside they contain polymeric material. Distinguish gas type The hose from the plumbing is easiest to be woven into the outer nut of the threads, they must be yellow.

Hoses in a metal lap inexpensive and easy to use, but some european countries Established a ban on their application. In our country, gas workers are also recommended to gradually refuse them or operate in compliance with precautions.

The plastic hose, which is inside, is exposed to the same destruction and destruction as rubber. Also, steel is a good conductor electric currentSo, the connection must be performed with the mandatory use of dielectric pads.

Stainless steel bellows bellows hose.

Silphon type hoses are the only gas services permitted for household gas appliances. What is the siltphone? This corrugated durable and dense shell, preserving its properties when exposed to temperature, pressure and serious mechanical load.

Silphon takes its name from the English. Corporate Sylphon. It happens one- and multi-layer type, manufactured from both metal and non-metallic materials. The shell serves as a barrier and gives the product enhanced security.

Silphon flexible sleeves are made of stainless steel. They are two types. The first in a metal fever without isolation, this type is suitable for conventional plates with traditional spiked spiked. If you have a modern gas stove equipped with an electronics and has a connection to the electrical network, then you should not bother myself searching for dielectric gasket.

It is easier to draw your gaze to the second type with a polymer coating of yellow color, which is reliable electrical insulation. This protection for gas stoves equipped with various electrical parts - electric climb, highlighted with electric coolers, is particularly relevant. Polymer coating - It is durable, firmly, reliably and guarantees absolute electrical insulation.

For uniform gas supply is recommended inner diameter Hose at least 10 mm. The advantages of using bitten hoses are indisputable. Samples with a plastic coating, guaranteeing excellent protection against various cataclysms proven itself particularly well.

Silphon sleeves have a service life of up to 30 years. The only drawback is high, compared with other types of gas hoses, cost, but here as they say, safety is more expensive! Moreover, the increased value in percentage will be negligible, compared with the acquired gas equipment.

Sylphon hose for gas, advantages:

• Gas hose is manufactured in accordance with technical Conditions and satisfies the regulations of the GOST;
• The only authorized government services;
• Component PVC coating provides product reliable protection. The polymers are perfectly opposed to the effects of aggressive media and mechanical shocks.
• Gas supplying is often unharmed, exposed to significant, and sometimes critical loads;
• On the product manufacturers set a long service life, more than 25 years;
• PVC protects against electrical effects in 1000 V and more.
• There are no standards for restrictions during operation.

How to choose the right gas hose

The main advice sounds quite trite: the gas hose without emergency consequences can be bought in any specialized store where you will be given a certificate of compliance with the state pattern. Acting on the question: what gas hose is better than a bellix or rubber, stop your choice in favor of the first. And of course, beware of cheap Chinese fakes or from other countries that do not care about the reputation of the company. On the street market you can find high-quality fakes in which:

Gas hose from very thin rubber to be rapid wear;
- Many fakes in appearance are completely indistinguishable from the present, especially if you are an ordinary buyer, not a professional employee gas service

Do not forget to check the availability of yellow color On the braid of the hose, it is she indicating that you have a gas hose in your hands, and not a water supply of water supply with a monolay-red color. We must buy a gas hose with a "stock", pre-make required measurements And add 20%, this length will be enough.

The manufacturer suggests different lengthsBut the most popular is one-two-meter options. Standard diameters Used in everyday life is 1/2 or 3/4 inches. Gas hose is equipped with two cape nuts with internal thread (American or in common mom-mom). The second type of hose, when at one end nut, on another bushing with an outer thread - "Mom-Papa".

Connecting the gas hose to the stove

After the purchase suitable option Products, with impatience, move to the hose connection to the new plate. Find behind the plates of the fitting as a rule, with an external thread. This is the inlet for supplying gas. Plate manufacturers are equipped with their own products depending on the model direct or angular receiver.

If you got a device with direct entrance, we advise you to purchase a brass angle with internal threads and the restrictive wall into which the parenchite gasket is invested. When installing, avoid harsh hose fluctuations.

Imported plates sometimes go on sale with a thread at an outlet 3/8 or 3/4 inches. There will be no tragedy if you in advance will additionally acquire the usual Futorca adapter on proportionate threads of your gas hose. IN residential buildings Gas riser is usually laid in one of the corners of the kitchen room. In your use, there is a removal, it must be installed on it. gas crane. We will screw up or screwed up our gas hose depending on what carvings are equipped with valve.

IN standard equipment The gas hose goes along with two paronit pads. Do not forget to use them during the connection, so it will be easier for you to achieve the lack of leaks. Advise the same, use the package purchased separately with a shallow mesh, the masters claim that it will help get rid of of different kind Pollution. But this procedure, we leave at your discretion, as usually gas comes without mechanical inclusions.

Gas hose is screwed wrenchBut do not pep and do not squeeze the paronite. After the work performed, it remains to carry out a check of a possible gas leakage. It is enough to apply a soap foam on the connections, the lack of air bubbles says that the work is made with a qualitative and stove you can use. Bon Appetit!

Compliance with the basics of security

• The main requirement of the gas management service is access to the eyeliner, so the flexible hose for the gas stove must be within reach;
• It is not allowed to have a third-party connection to the gas stove;
• The gas hose must be kept clean, the embellishment is not allowed, it is impossible to cover its paint, and produce other "improvements" of the appearance;
• The eyeliner must have a natural sagging. The tension is fraught with a cliff of the hose, or a gas leakage in the places of attachment to the fitters;
• If you are planning to move the slab before general cleaning, in advance, calculate the required length of the gas hose. Be sure to start the ball valve before the start of movement;
• Do not allow strong bends and twisting;
• It is necessary to protect the metal braid from condensate;
• Do not expose welding or soldering, use only threaded method docking;
• Provide the replacement of the old gas hose in a timely manner, in accordance with the service life of the installed manufacturer.

We really hope that our review helped to decide and understand which gas hose for the gas stove is better to choose. Now you definitely do not "get lost" in the store, as we learned the species features and differences between gas hoses from each other. An independent connection will also not take much time in the presence of the necessary tools.

However, pay attention to the fact that a number of manufacturers do not allow for similar works by the owner of the technique. One of the requirements, the condition is increasingly becoming a connection of instruments by specialists of the authorized gas service. Otherwise, there is a risk of losing a guarantee. Specify the operating instructions, do you lose warranty obligations on the slab in case independent connection. If not, we wish good luck!

We offer you an entertaining video review, where on 1 channel it is recommended which gas hose is better to use in a home source:
