I'm looking for a gas-safe O-ring for a gas fire, but I'm struggling to find anywhere that actually specifies what would be suitable.
For a bit of context: I have a Kinder Oasis gas fire, and it was found to be leaking from an elbow connector (B1490), but the engineer who found the leak said that rather than replacing the whole joint, it should just be possible to get a new O-ring. Unfortunately Kinder have not been forthcoming with any details! Can anyone suggest what I should be looking for?
