I have been trying to get a good seal on a shower valve that uses male iron fittings to compression. The shower valve has the female.
I have tried ptfe tape and it works (sort of) does anybody know of a better way of getting a good seal? I think it needs a washer at the end to stop the metal - metal contact, but I can't find one big enough!
It is starting to drive me mad.....
Try an O-ring. Im guessing its 3/4 inch if it to a thermostatic value? Failing that - ptfe is wonderful stuff, apply more so it locks the joint before you get the metal on metal stage.
Lard.
It is a 1/2 inch fitting and I have now completed this task by using loads and loads of ptfe tape. For something that is going to be buried away and forgot about, I would think there would be a better way of connecting the valve!
Pipe joint compound Something like this or similar.
Test the joint before youu bury it though
