Hi All, Can anybody tell me, how many turns of PTFE tape is required on radiator joints? I have been told that it should be 10 to 12 turns, but I usually use 3 to 5 turns of PTFE on CH joints which hasn’t been much of a problem to me so far. (Apart from an occasional leak on the first test anyway!)

"Hi Harry, I do use the 10 to 12 turns of PTFE myself and I’d recommend sticking with it – it’s never been a problem to me. Your mileage may vary a bit, but just check that it is biting as you wind it. At worst, start using 10 to 12 turns - if only to avoid your occasional leaks."

"About 8 for me. Wind in and out half way. Jointing compound. Then wind all the way. Never leaks"

"This one is down to experience I always use min 6 turns depending on if the thread is new and if there are any tension on the joint. I also use a tread paste in all instance as a fail save. I apply the paste on top of the thread.

The best way is to get a plumber round to do the job that way there shouldn't be any great concerns for leaks"

"On radiators I go for belt and braces approach 8 turns of ptfe and some liquid ptfe on internal threads. Never had a leak yet using both and as its not pottable water, why not ????"

"5-6 turns is the recommended amount. 3 isn't really enough and 10-12 is too many. Personally I use jointing compound as well to guarantee leak proof joints."
