yes and it was fine winding it in but even when very tight it still drips very slowly. I will try tapering the tape as advised in the last post and see what happens. Thanks
just finished plumbing in a bathroom and amazingly all my soldering does not leak however having a complete nightmare trying to stop the radiator fittings from leaking. The leaks are from 1/2 inch fitting that goes into radiator. Tried loads of ptfe tape and very tight but still leaking. Any ideas?
