The oil supply-pipe to my oil boiler has started weeping at the junction where it goes into the shut-off valve.
I've tried tightening the nut (which clamps down on the olive) but it still weeps.
I guess I need to take the joint apart and put some sealant on the olive, then re-assemble the joint.
The question is - what kind of sealant? PTFE tape (or would the oil dissolve that?)?
(The obvious alternative is to take the joint apart, cut off the last inch and reassemble with a new olive - but this isn't possible because the ****** who assembled it in the first place cut the pipe so short that there's not enough left to do this :-( )
Any suggestions?
Ta!
