Since the emergence of the first gas-powered devices, which were only connected with a jet pipe, until today, many things have changed decisively (fundamentally). Flexible gas hoses have become commonplace, they are much more convenient to use, easier and quicker to connect.
Not sure which gas hose fits best? Let's take a look at different types of gas hoses together. In the article you will find the most important selection criteria to make the right decision.
- A gas hose must be connected firmly and absolutely tightly. It is therefore necessary to get a suitable connection.
- All gas hoses are available in different lengths. The most commonly used hoses are 1, 1.5 and 2 metres. It reduces the risk of hose rupture and thus ensures safety.
- For an easier and faster assembly, a cleanly processed thread plays a major role.
- Visual you can also easily see whether the material of the gas hose is of high quality. Quality products tend to have a matt surface.
The Best Gas Hoses: Our Picks
In any DIY shop or online shop, there are many models and options for gas hoses that differ in length, manufacturing material and other features. It makes sense to know beforehand for which application you want to use the gas hose. Here you can find the best gas hoses based on different options.
Buying and evaluation criteria for gas hoses
You must remember that you cannot connect every gas hose yourself. Some require installation by qualified personnel. Gas hoses, gas regulators, everything related to gas that is installed in the vehicle and indoor gas appliances must be checked every 2 years by a specialist. This is called a gas inspection.
Hose core material
The hose core plays an important role in the pipe. It is particularly important that the materials used in production are resistant. That is why gas hoses are made of nitrile rubber (NBR), styrene-butadiene rubber (SBR) or chloroprene rubber (CR).
Hoses with an NBR core are suitable for various liquid gases. SBR gas hoses are particularly suitable for the supply of welding gases. Special hoses made of CR are fire-resistant and are also mostly self-extinguishing.
The choice of hose cover depends on the place of use. The most commonly used materials for the hose cover are SBR, NBR, polyvinyl chloride (PVC), chlorosulphate polyethylene (CSM) and ethylene propylene diene rubber (EPDM). These provide protection against abrasion, heat, ageing, weathering and various oils.
The diameter is divided into an inner diameter and an outer diameter. For gas hoses, an inner diameter of three to ten millimetres is the rule, for gas barbecues an 8mm hose is most commonly used. The outer diameter can be up to 30 mm, depending on the safety level.
A hose is suitable up to a pressure of 10 bar. The majority of gas appliances do not need such a high pressure, pressure reducers are used for this. If the garden barbecue, 2-flame cooker or similar is connected directly to the gas bottle with a gas hose and gas regulator, the pressure must always be 50 mbar in Germany. The gas cooker, gas regulator, gas cooker, the absorber or gas systems in mobile homes, caravans or campers are designed for 30mb.
The durability of a hose depends on the brand and material. However, there are two important criteria:
- According to technical rules, a gas hose should be replaced every eight to ten years.
- In case of defects, if your gas hose has any visible or invisible damage (e.g. gas smell, whistling noises on the hose), the hose should be replaced. If you are simply not sure, it is better to dip the gas line for your own safety.
There are many factors when choosing gas hoses. In order for your appliance to function safely and without risk, you need a gas hose that complies with all standards. Buy the hose from a certified dealer. Pay attention to the durability of gas hoses and regulators. With the right choice of product, most mistakes can be avoided right from the start.
