I have disturbed the bayonet fitting on my gas cooker and there is a VERY slight leak, seems to be coming up the thread where the bayonet fits on to my supply pipe.
I know that a I should really call the Corgi man, but I'm considering re-sealing it myself.
I noticed that when it was origiinally fitted, the fitter use some sort of cement to run down the thread, prior to tightening. Could someone tell me what I should use to ensure there are absolutely no leaks.
