In comparison with a rubber hose, the service life is increased by more than 2.5 times. The material is slow-burning, dielectric, withstands the test of contact with a hot plate.

Compared to bellows piping, it has a lower cost with a comparable service life and basic performance characteristics. Does not require additional dielectric insert. Installation of gas hoses is carried out by specialists of organizations licensed for the right to manufacture gas hazardous work with a mandatory mark in the passport of the date of installation or service work, the contractor, organization and license number. If these conditions are not observed, the manufacturer is not responsible for violation of the installation and operation rules.

A gas hose, it would seem, what kind of mystery can there be in this simplest product? came to any hardware store, took and forward to the cashier. However, have you ever wondered how the gas hose differs for gas stove and gas hose for ?

And most importantly, on the shelves of large retail chains such as Leroy Merlin or Maksidom, this product is presented simply in huge assortment. Involuntarily, the question arises: which gas hose is better to buy? On one tray there is a pvc gas hose reinforced with polyester thread, on the other a bellows-type gas hose, and even lower there is a rubber hose in general, and how not to get confused here?

More recently, just a couple of decades ago, you would not have been worried about the question of how to attach a gas stove. All gas household appliances, after purchase, were “tightly” and reliably connected, as a rule, by the master of their nearest housing office using a steel pipe. Of course, they didn’t even think about aesthetics or design. There was only one task - to start using the new device as soon as possible.

Accession steel pipe undoubtedly has a number of advantages. Requirements such as strength, reliability, safety are 100% guaranteed. That's just there is a small inconvenience, most likely it will not work for the hostess to wash the floor under the stove for the next twenty years. And kitchen furniture can't find right size, so that remains 20 centimeters on each side of the plate, but it is not possible to move it. Finally, such problems are a thing of the past, and there is no shortage on the domestic economic market for a long time, and flexible gas supply is offered in a large assortment.

Choosing a gas hose for a stove or boiler is a very serious step. The lives of many people depend on its strength, reliability and safety. Often, the result of an illiterate connection of a stove or gas column to communications is an explosion. For flexible piping natural gas only special gas hoses are used. Tap water is strictly prohibited for this purpose.

Of course, it is better to call a master who will provide a professional connection and give a guarantee. Each of us has seen in the news what household gas explosions lead to, including as a result of unqualified connections of household gas appliances. We know from childhood that you can’t joke with gas. However, a modern gas hose allows you to connect yourself. Adhering to elementary safety rules, any adult man is able to perform such a procedure.

So let's go to the store. Let's see what the seller offers there, which flexible gas hose to choose and buy for a gas stove? It turns out that there are three main types of gas hoses used in everyday life:

  • - rubber-fabric;
  • – rubber reinforced;
  • - bellows.

The gas hose is rubber.

The softest of all hose types are rubber hoses reinforced with textile thread. They have long earned a reputation for being an unpretentious compound, and are often found in the economy of a prudent homeowner. Simple installation work, low cost, flexible properties and functionality are attractive qualities that determine the popularity. On the shelves there are always available options with different lengths and diameters.

Rubber is one of the best materials dielectrics. They are used to supply household appliances liquefied gas from gas cylinders and are used in cottages and private homes. This method of flexible gas supply is the simplest and cheapest, but also most dangerous.

The big disadvantage is that over time, cracks form in the rubber, leading to gas leakage. The only place where this type of flexible piping is allowed is gas cylinders in the private sector. Among other things, the products lack the necessary rigidity.

It is not recommended to use rubber-fabric sleeves for more than two years, but in practice they are used much longer.However, modern rubber hoses are made with the inclusion of elastic components which allow the product to be used for up to 5 years.

Reinforced gas hose.

The most common rubber reinforced sleeves that look like hoses for water supply. Outside, they are braided with steel threads. Although they are called rubber, inside they contain polymer material. Distinguish gas type the hose from the water supply is the easiest to color the threads woven into the outer braid, they should be yellow.

Braided hoses are inexpensive and easy to use, but some European countries have banned their use. In our country, gas workers also recommend gradually abandoning them or operating them with precautions.

The plastic hose inside undergoes the same destruction and destruction as rubber. In addition, steel is a good conductor. electric current, so that the connection must be made with the obligatory use of dielectric gaskets.

Stainless steel bellows type gas hose.

Bellows type hoses are the only ones approved by the gas authorities for domestic gas appliances. What is a bellows? This is a corrugated, durable and dense shell that retains its properties when exposed to temperature, pressure and severe mechanical stress.

The bellows takes its name from the English. branded Sylphon. It can be single- and multi-layer type, made of both metallic and non-metallic materials. The shell serves as a barrier and gives the product increased safety.

Bellows flexible hoses are made of of stainless steel. They are of two types. The first in a metal braid without insulation, this type is suitable for conventional stoves with traditional match ignition. If you have a modern gas stove equipped with electric ignition and has an electrical connection, then you should not bother looking for a dielectric gasket.

It is easier to turn your attention to the second type with a yellow polymer coating, which is a reliable electrical insulation. Such protection is especially relevant for gas stoves equipped with various electrical parts - electric ignition, lighting, electric grill. polymer coating- it is durable, strong, reliable and guarantees absolute electrical insulation.

For uniform gas supply, an inner diameter of the hose of at least 10 mm is recommended. The benefits of using bellows hoses are undeniable. Particularly well proven are samples with a plastic coating, which guarantees excellent protection against various cataclysms.

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

Bellows gas hose advantages:

  • The gas hose is manufactured according to specifications and satisfies the regulatory provisions of GOST;
  • The only one approved for use by government services;
  • Component PVC coating provides the product with reliable protection. Polymers perfectly resist the effects of aggressive environments and mechanical shocks.
  • The gas supply line often remains unscathed, subjected to significant and sometimes critical loads;
  • Manufacturers set a long service life for the product, more than 25 years;
  • PVC protects against electrical influences of 1000 V or more.
  • There are no rules for restrictions during operation.

How to choose the right gas hose

The main advice sounds quite banal: you can buy a gas hose without emergency consequences at any specialized store where you will be given a state-approved certificate of conformity. When answering the question: which gas hose is better than bellows or rubber, opt for the first one. And of course, beware of cheap Chinese fakes or from other countries that do not care about the company's reputation. On the street market you can find high-quality fakes in which:

Gas hose made of very thin rubber, subject to rapid wear;
- lots of fakes appearance are completely indistinguishable from the real ones, especially if you are an ordinary buyer, and not a professional employee gas service

Remember to check for a yellow mark on the hose sheath, it is she who indicates that you have a gas hose in your hands, and not a water supply with a blue-red mark. Nes is worth buying a gas hose with a “reserve”, first make the necessary measurements and add 20%, this length will be enough.

The manufacturer offers different lengths, but the most popular are one-two-meter options. Standard diameters used in everyday life are 1/2 or 3/4 inches. The gas hose is equipped with two union nuts with internal threads (American or common mother-mother). The second type of hose, when at one end there is a nut, at the other there is a sleeve with external thread- "mother, father".

Connecting the gas hose to the stove

After the purchase suitable option products, we are looking forward to connecting the hose to the brand new stove. We find a fitting at the back of the plate, as a rule, with an external thread. This is the gas inlet. Plate manufacturers complete their products, depending on the model, with a straight or angled receiver.

If you got a device with a direct entry, we advise you to purchase a brass angle with internal threads and a restrictive wall into which a paranitic gasket is inserted. When installing, avoid sharp kinks in the hose.

Imported plates sometimes go on sale with a 3/8 or 3/4 inch thread at the outlet. There will be no tragedy if you, in advance, additionally purchase a regular “futorka” adapter for the commensurate threads of your gas hose. AT residential buildings the gas riser is usually laid in one of the corners of the kitchen. There is a branch for your use from it, it must be installed on it gas cock. We will screw or screw our gas hose onto it, depending on which thread the valve is equipped with.

As standard, the gas hose comes with two paronite gaskets. Don't forget to use them when connecting, so it will be easier for you to ensure that there are no leaks. It is also advised to use a separately purchased pad with a fine mesh, the masters say that it will help get rid of all sorts of contaminants. But we leave this procedure to your discretion, since gas usually enters without mechanical inclusions.

The gas hose is screwed on with a wrench, but do not overdo it and do not squeeze out the paronite. After the work has been completed, it remains to carry out a mandatory check for a possible gas leak. It is enough to apply soap foam to the joints, the absence of air bubbles indicates that the work is done with high quality and the stove can be used. Enjoy your meal!

Compliance with the basics of safety

  • The main requirement of the gas facilities service is access to the supply, thus flexible hose for a gas stove must be within reach;
  • It is not allowed to have third-party connection of devices to the gas stove;
  • The gas hose must be kept clean, embellishment, paint, and other “improvements” of appearance are not allowed;
  • The eyeliner should have a natural sag. Tension is fraught with a hose break, or gas leakage at the points of attachment to the fittings;
  • If you plan to move the plate before general cleaning, calculate the required length of the gas hose in advance. Be sure to close the ball valve before moving;
  • Avoid strong bends and twists;
  • It is necessary to protect the metal braid from condensate;
  • Do not weld or solder the connection, use only the threaded docking method;
  • Timely replace the old one with a new gas hose, in accordance with the service life established by the manufacturer.

We really hope that our review helped to decide and understand which gas hose for a gas stove is better to choose. Now you will definitely not “get lost” in the store, as you have learned the specific features and differences between gas hoses from each other. Self-connection also does not take much time if you have the necessary tools.

However, please note that a number of manufacturers do not allow the owner of the equipment to do such work. One of the requirements is increasingly becoming the condition for the connection of devices by specialists of an authorized gas service. Otherwise, there is a risk of voiding the warranty. Check in the instruction manual whether you lose the warranty on the stove in the event of self connection. If not, then good luck!
