Regulator and hose: when to replace them
LPG hoses carry an expiry date and should be replaced before it passes. Use only OGRA-certified regulators, keep the hose visible rather than hidden behind a unit so damage can be seen, and turn the regulator off when you are not cooking.
The cylinder is the part people worry about. The hose and regulator are the parts that actually fail.
Does an LPG hose have an expiry date?
Yes. Unlike the cylinder, the hose does carry a date, usually printed along its length. Replace it before that date rather than after.
Rubber hardens and cracks with heat and age, and a kitchen is a hot place. A hose that looks fine can be brittle inside.
What should you check on a hose?
- Cracks or crazing, especially within a few centimetres of each end
- Hardening — a good hose flexes, an old one resists
- Swelling, softness or a sticky surface
- Cuts, abrasion, or scorch marks
- Clips at both ends, tight and in place
If any of those are present, replace it. A hose is inexpensive next to what it protects.
Why must the hose stay visible?
Because you cannot inspect what you cannot see. A hose run behind a fitted unit or under a counter hides exactly the cracking and abrasion you need to catch.
Route it so its whole length is in view, without kinks and without touching a hot surface.
What about the regulator?
Use only an OGRA-certified regulator. It is the component controlling the pressure reaching your burner, and an uncertified one is not a saving worth making.
Check that it seats squarely on the valve and that the O-ring or bull nose is present and undamaged. Replace the regulator if it is corroded, if it rattles, or if it will not seat cleanly.
Should you turn the regulator off between meals?
Yes. Closing it when you are not cooking means that if the hose does fail, it fails against a closed valve rather than a live cylinder.
It takes a second and it is the cheapest safety habit available.
Common questions
How often should I change my gas hose?
Before the expiry date printed on it, and immediately if you see cracks, hardening, swelling or abrasion. Rubber degrades with kitchen heat, so a hose that looks intact can still be brittle.
Where should the gas hose be routed?
Along a visible path, not hidden behind a unit or under a counter. You cannot inspect what you cannot see, and cracking usually starts near the ends.
Should I turn off the regulator when not cooking?
Yes. With the regulator closed, a hose failure happens against a closed valve rather than a live cylinder. It takes a second and it is the cheapest safety habit there is.
