I've just fitted a new radiator but cannot stop one of the tails from leaking. It's a taper thread and I've used PTFE tape, but despite three attempts including two different tails, it still drips.
The design is such that you screw the tail into the rad and tighten a large nut on the tail onto the valve. Because tightening the nut onto the tail can undo the taper thread, I'm very careful not to overtighten it and move the taper thread.
I've never had a problem with these radiators or this tail design in the past, but I'm starting to lose patience.
Any thoughts what I should use to seal it?
More PTFE tape?
Plumbers Mait?
Silicone sealant?
Loctite thread lock?
PS it's my house so I'm not after a bodge that can't be undone!
TIA
