The drain plug on my radiator (2007 +4, plastic rad) has been weeping for a while. I have tried tightening the tap a couple of times which seemed to help.

But I'm hesitant to tighten it anymore if case I break it.

It is not a major issue but it is annoying, I thought about unscrewing the tap a few turns and putting on plumber's PTFE tape and then screwing back up.

Any thoughts or experiences?
