Gas hose, it would seem, what mystery could there be in this simplest product? Come to any hardware store, take it and go to the checkout. However, have you ever wondered what the difference between a gas hose is? gas stove and a gas hose for?

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

More recently, literally a couple of decades ago, you would not have worried about the question of how to connect a gas stove. All gas household appliances, after purchase, were “tightly” and securely connected, as a rule, by the foreman of their nearest housing office using a steel pipe. Of course, we 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, and safety are 100% ensured. There’s just one small inconvenience: the housewife most likely won’t be able to wash the floor under the stove for the next twenty years. AND kitchen furniture I can’t find the right size, so I’m left with 20 centimeters on each side of the slab, but it’s not possible to move it. Finally, this kind of problem is a thing of the past, and there has been no shortage on the domestic household market for a long time, and flexible gas supply is offered in a wide range.

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 water heater to communications is an explosion. For flexible liner natural gas Only special gas hoses are used. It is strictly prohibited to use tap water for this purpose.

Of course, it is better to call a specialist 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 we cannot joke with gas. However, a modern gas hose allows you to make the connection yourself. Adhering to basic safety rules, any adult man can 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 there are three main types of gas hoses used in everyday life:

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

Rubber gas hose.

The softest of all types of hoses are rubber hoses reinforced with textile thread. They have long gained a reputation as an unpretentious compound, and are often found in the household of a thrifty homeowner. Simple installation work, inexpensive cost, flexible properties and functionality are attractive qualities that determine popularity. There are always options on the shelves with different lengths and diameters.

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

The big disadvantage is that over time, cracks form in the rubber, leading to gas leakage. The only place where it is permissible to use this type of flexible liner 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 last much longer.However, modern rubber hoses are made with the inclusion of elastic components , which allow you to use the product for up to 5 years.

Reinforced gas hose.

The most common are rubber reinforced hoses that look like hoses for water supply. On the outside they are braided with steel threads. Although they are called rubber, inside they contain polymer material. Distinguish gas type For a water supply hose, it is easiest to identify the color of the threads woven into the outer braid; they should be yellow.

Braided hoses are inexpensive and easy to use, but some European countries established a ban on their use. In our country, gas workers also recommend gradually abandoning them or using them with precautions.

The plastic hose inside is subject to the same destruction and destruction as rubber. In addition, steel is a good conductor electric current, so 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 gas services for household 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 load.

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

Bellows flexible hoses are made of stainless steel. They come in two types. The first in a metal braid without insulation, this type is suitable for ordinary stoves with traditional ignition from matches. If your modern gas stove is equipped with electric ignition and is connected to the electrical network, 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 reliable electrical insulation. This protection is especially relevant for gas stoves equipped with various electrical components - electric ignition, lighting, electric grill. Polymer coating- it is durable, strong, reliable and guarantees absolute electrical insulation.

For uniform gas supply, an internal hose diameter of at least 10 mm is recommended. The advantages of using bellows hoses are undeniable. Samples with a plastic coating, which guarantee excellent protection from various disasters, have proven themselves especially well.

Bellows hoses 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 purchased gas equipment.

Bellows hose for gas, advantages:

The gas hose is manufactured in accordance with technical 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 are highly resistant to aggressive environments and mechanical shocks.
The gas supply line often remains undamaged, subjected to significant and sometimes critical loads;
Manufacturers install on the product long term service, more than 25 years;
PVC protects against electrical influences of 1000 V or more.
There are no regulations regarding restrictions during operation.

How to choose the right gas hose

The main advice sounds quite banal: a gas hose without emergency consequences can be bought at any specialized store where you will be provided with a state certificate of conformity. When answering the question: which gas hose is better, bellows or rubber, opt for the first. And of course, beware of cheap ones 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;
- many fakes appearance completely indistinguishable from the real thing, especially if you are an ordinary buyer and not a professional gas service employee

Don’t forget to check for the presence of a yellow mark on the hose braid; this is what indicates that you have a gas hose in your hands, and not a water supply line with a blue-red mark. It is not worth buying a gas hose with a “reserve”, first take the necessary measurements and add 20%, this length will be enough.

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

Connecting the gas hose to the stove

After purchase suitable option products, we eagerly move on to the steps of connecting the hose to the new stove. We find a fitting at the back of the plate, usually with an external thread. This is the gas inlet. Slab manufacturers complete their products with a straight or angular receiver, depending on the model.

If you get a device with a direct entry, we recommend purchasing a brass angle with internal threads and a boundary wall into which a paranitic gasket is inserted. When installing, avoid sharp bends in the hose.

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

As standard, the gas hose comes with two paronite gaskets. Remember to use them when connecting, this will make it easier for you to ensure that there are no leaks. They also advise using a gasket with a fine mesh purchased separately; experts claim that it will help get rid of various kinds pollution. But we leave this procedure at your discretion, since gas usually flows without mechanical inclusions.

The gas hose is screwed on wrench, but do not overdo it and do not squeeze out the paronitis. After the work has been completed, it remains necessary to carry out a mandatory check for possible gas leaks. Simply apply to connections soap suds, the absence of air bubbles indicates that the work was done efficiently and the stove can be used. Bon appetit!

Maintaining Basic Safety

The main requirement of the gas service is access to the supply line, so the flexible hose for the gas stove must be within reach;
It is not allowed to have third-party connections to the gas stove;
The gas hose must be kept clean, embellishment is not allowed, it cannot be coated with paint, or other “improvements” in appearance are made;
The eyeliner should have a natural sag. Tension is fraught with a break in the hose, or gas leakage at the points of connection to the fittings;
If you plan to move the slab before spring cleaning, calculate the required length of the gas hose in advance. Be sure to close the ball valve before moving;
Avoid excessive bending or twisting;
It is necessary to protect the metal braid from condensation;
Do not weld or solder the connection, use only the threaded joining method;
Replace the old gas hose with a new one in a timely manner, in accordance with the service life established by the manufacturer.

We really hope that our review helped you decide and understand which gas hose for a gas stove is best to choose. Now you definitely won’t get lost in the store, since you have learned the specific features and differences between gas hoses. Self-connection will also 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 perform such work. One of the requirements is increasingly becoming the condition for connecting devices by specialists of an authorized gas service. Otherwise, there is a risk of losing the warranty. Check in the operating instructions whether you will lose the warranty on the stove if self-connection. If not, we wish you good luck!
