So now the cold weather is really with us, I decided it was time to commission the Screwfix towel rail I fitted way back at the start of the summer.
One of the two entries for the valve tails won't stop leaking despite copious amounts of thick PTFE tape (attempt 1) or PTFE paste (attempt 2) it doesn't feel like they're tapered threads , so usually I'd expect that a doubty/o-ring seal is what I'd require. As the valve are on the heating pipes and live, I don't really have the option to go for another style of fitting.
What's the best thing to clag it together with?
