Gas stove hose: which is better, maximum product length

Not so long ago there was no question about which hose for a gas stove to choose. In Soviet times, these household appliances were tightly connected with steel pipes to the gas pipeline. It was simple, reliable, safe, but inconvenient: the plate could not be moved after installation even a millimeter. With the advent of a new product, it became possible to connect the plate with a flexible hose, so that the device can be rearranged or temporarily moved if necessary. But which eyeliner to choose?

Gas hose requirements

1. Flexible eyeliner is a complete product, any connections (couplings, extension cords) are unacceptable. You cannot make one out of two hoses.
2. The hose must be oil resistant and not subject to corrosion.
3. Compliance of the hose with the parameters of the gas used is mandatory.
4. Flexible eyeliner must be provided access (it must not be placed in boxes, strobes, etc.).
5. Use hoses with a service life of at least 10 years.

The maximum permissible eyeliner length is indicated by the manufacturer of the gas stove. For example, the European standard: EN14800: 2003 - two meters. The maximum length of a certified gas hose is 7 meters.

In GOST there are no direct instructions on the sizes!

How long are gas hoses?

The most common eyeliner sizes are as follows (in centimeters):

• 30;
• 40;
• 50;
• 60;
• 80;
• 100;
• 120;
• 150;
• 200;
• 250;
• 300;
• 350;
• 400;
• 450;
• 500;
• 600;
• 700.

Types of hoses

Today, several types of hoses are used to connect the gas stove:

• oxygen;
• rubber fabric;
• reinforced rubber;
• rubber with a metal braid;
• reinforced from PVC;
• bellows.

It is worth considering them in more detail before choosing the right one.

Oxygen

Oxygen hoses were often used in Soviet times, as there were simply no other options for connecting through a flexible eyeliner. Now this product is fading into the background. Cost - from 60 rubles per meter running without tips.

Positive traits:

• ability to withstand high pressure (up to 20 atmospheres);
• ease of installation;
• cheapness;
• does not conduct electricity;
• can be selected for any pipe diameter.

At the same time, oxygen products are short-lived and require an attentive relationship:

• they cannot be painted;
• inner diameter should exceed 1.6 cm;
• must not be in oil, otherwise the rubber will overheat, which will lead to its destruction, cracks and gas leak.

It is important to remember that the oxygen connecting hose is not a special gas hose, it is needed for other purposes, so it is better not to use it unless absolutely necessary.

Rubber fabric

The cheapest of specialized components from 120 rubles for 0.5 meters with tips (finished product). Rubber-fabric hose has:

• relatively short service life, on average from 5 years, depending on the quality of the materials used;
• insufficient level of rigidity;
• low permissible temperature;
• product length from 0.4 to 7 meters.

Otherwise, a good option for connection plate having its advantages:

• high level of electrical insulation;
• wide range (easy to find for any pipes);
• due to its softness, it is easily trimmed under the existing conditions.

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

Metal braided

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

The gas hose is similar to a water pipe (for a toilet, faucets, shower). You can distinguish it by marking: plumbing products have blue and red marks for cold and hot water, a yellow thread is woven into the braid of gas.

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

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

Do not use the product without installing a dielectric insert!

PVC reinforced

PVC gas piping is one of the latest developments. It does not conduct electricity, does not collapse like a rubber, and is almost as durable as a bellows hose. It has 2 layers: the inner one is made of black PVC, and the outer shell is made of yellow PVC. Due to the novelty, not all gas services accept them for operation, so it is better to consult an authorized organization in advance. The price for 60 cm of the product is from 140 rubles.

Properties of reinforced PVC hoses:

• slow-burning;
• dielectric;
• passes the test of contact with a hot plate;
• quite cheap with a comparable service life;
• resistant to oil mist;
• operated in conditions of increased loads;
• complies with the requirements of GOST R 52209-2004, GOST12.2.063-81, GOST12.2.003-91;
• Warranty period of service - 12 years; real service life - more than 20 years;
• length from 60 cm to 5 m.

Bellows

Bellows tubes are most often recommended by specialists in gas equipment installation. This option is the most reliable and most expensive. But given the very long service life (up to 30 years), its cost is justified. Price from 170 rubles for 60 cm of finished eyeliner.

Bellows (from the English. brand name Sylphon) - an elastic single-layer or multi-layer corrugated shell made of metal, non-metallic and composite materials, preserving strength and tightness during multi-cycle compressive, tensile, bending, and combinations thereof under the influence of internal or external pressure, temperature, and mechanical stresses. (https://ru.wikipedia.org/wiki/Сильфон)

The bellows hose is made of stainless steel, with a PVC coating on top. This ensures that it will last a long time: the average life is 25-30 years. A metal braid reliably protects against mechanical influences, and a polyvinyl chloride coating provides electrical insulation and resistance to chemicals. Thanks to the corrugated surface, the product bends easily.

The bellows gas hose has the following advantages:

• can be connected to any gas equipment: stoves, boilers, etc .;
• has the connecting sizes 1/2 ″, 3/4 ″, 1 ″;
• has great flexibility;
• withstands pressure up to 6 atmospheres;
• wide range of operating temperatures: from -50 to +250 degrees (installation on the street is allowed, nothing will happen to it when it touches hot surfaces);
• able to withstand mechanical stress, aggressive environmental effects, household chemicals;
• hoses meet the requirements of GOST R 52209-2004, GOST12.2.063-81, GOST12.2.003-91;
• Warranty period - up to 15 years;
• service life - up to 30 years;
• able to ensure the tightness of the system even under extreme loads, for example, during an earthquake.

The length of the bellows gas hose varies by manufacturer.

At "Emiflex" eyeliner can increase in size by 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 Eliteline hoses have a fixed length (in meters):

• 0,3;
• 0,4;
• 0,5;
• 0,6;
• 0,8;
• 1,0;
• 1,2;
• 1,5;
• 1,8;
• 2,0;
• 2,5;
• 3,0;
• 4,0;
• 5,0.

The only thing that can scare away the buyer is the price. But given its longevity, it is the most profitable acquisition.

Do not use the hose without installing a dielectric insert!

Gas hose selection rules

A few simple tips will help you choose a gas hose, save time and money and avoid the troubles of energy leakage:

• Buy any products only in specialized stores, and do not forget to ask the seller for a quality certificate.
• You cannot buy Chinese hoses: they are thin and quickly become unusable. There are also many fakes.
• The plates are connected only by those sleeves on which there is a special yellow mark. You can not replace them with plumbing. The latter are not designed for such loads and wear out in a few weeks.
• When buying eyeliner, you need to carefully inspect for damage.
• Select the size so that the product sags, but does not stretch.
• Pay attention to the mounting methods - fitting or nut - select them according to size.

Important! For a stove with electric ignition, you need to buy a fireproof flexible eyeliner with insulators in the form of white plastic rings between the nuts and the braid or use a dielectric insert.

Installation Recommendations

When installing the hose, you must use the following recommendations:

• The sleeve should be laid in an easily accessible place. It is not safe to hide it in a wall or under the floor.
• The bending radius should not be less than three times its diameter.
• The product must not be pulled, twisted, bent, or painted.
• Metal parts must be protected from condensation, leading to oxidation of the material.
• Do not connect steel elements (tips) with copper, this is fraught with electrolytic damage to the product. Allowed combinations are steel with steel, brass with copper.
• Tighten all joints tightly, but without excessive force so as not to damage the threads.
• A dielectric insert is installed between the tap and the gas hose, which prevents the accumulation of stray currents, which can lead to overheating of the braid, breakage of the device, and melting of rubber.

Gas supply life

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

Guaranteed service life is indicated in the product passport and in the certificate of conformity.

• rubber hoses (with and without sheath) - a guarantee of 5 years, a service life of up to 10 years;
• PVC eyeliner - 12 year warranty, lasts up to 20 years;
• bellows gas hose - 15 year warranty, does not require replacement up to 30 years.

Which gas hose is better?

1. In terms of the ratio of technical characteristics and cost, the leader is a bellows gas hose; it is not for nothing that gas workers themselves recommend it. Do not forget to install a dielectric insert with this product!
2. Next comes the gas hose made of PVC, it is less durable, but does not require electrical protection, is not destroyed by oil.
3. In the last place is a rubber eyeliner. It has the shortest service life and poor durability. But it is the most affordable.
