A gas hose must be replaced once every 5 years. If damage occurs, for example small cracks, the gas hose must be replaced at once. The gas hose must have the GASTEC quality mark, followed by a year: this is the production date. This date plus 5 years is the date on which it must be replaced at the latest.
An approved gas hose (propane/butane) has the imprint: NEN5654.
- Always use a hose that is suitable for the type of gas you are using and choose a hose that is marked with the year and the name of the manufacturer.
- We recommend replacing a gas hose every 5 years. This is because sunlight, heat and the flowing gas age the rubber.
- Gas hoses must be checked yearly for wear, leakage and damage. If there is discolouration, deformation, damage or signs of porosity, replace the hose immediately. Do not take any risks, if in doubt replace the hose!
- Because you have to take some pressure loss into account, keep the gas hose length as short as possible. Never allow the gas hose to become kinked or twisted.
- Keep the gas hose away from heat sources and UV light (solar radiation).
- Never use an open flame to find a leak. You do this with soapy water.
Always open and close the gas tap by hand. Do not use any tools or force to open the gas tap. If you cannot open the gas tap, return the gas bottle to your supplier.
Loosen and tighten the gas hose with pressed couplings (swivels) with a wrench or pliers, without using force. So, hand tight is not enough.
If a gas hose is fitted with hose clamps, check these extra carefully, because tightening the hose clamp damages the gas hose more quickly and can tear at those points.
