`white tape` for making watertight joints..........how much

juco · 26 Oct 2006

As a general guide how much tape should be wrapped around the threads of joints to make them watertight. ?

thanks

If it's the good old PTFE tape, then about 3-4 nice tight turns will do.

i go round 14 times on a 1/2 rad tail and it works good . remember to go the opposite way to the threads .

Your meant to follow the thread. Eg looking at it end on your would apply it clockwise. Doing it your way, it will loosen off and scrunch down as you are tightening the fitting, thus making it leak.

i wrap so much round. so that it all bunches up at the end . when you tighten it

and completeley defeat the point. ......

OK guys based on the answers so far .... between 3 wraps and a full roll.

I`ll go for around 6 (wraps) and see what happens.

If you making what's commonly termed an "iron" joint, then use as much tape as is required to make a seal.

If you're making a compression joint, then by all means wrap 4 to 5 turns of PTFE on the wet joint side of the olive, but don't put any PTFE on the threads of any compression joint fitting.

At all.

Ever.

EVER.
