Leaking Rad tail Extensions

[Serval]

I’ve got these rad tail extension pieces from tool station
Radiator Valve Extension 25mm - Toolstation

Ive tried a couple of times and I can’t get a decent seal on them using ptfe.

Will give it one more go and use more ptfe but if they continue to weep im wondering if it is feasible to use hawk white on them instead as ive i have a tin of that in the shed.


Cheers

How many turns you using 12 - 14 needed bit of hawk won't hurt but not needed really paste the olive and rad valve union with it though good luck kop

Sack them off and use the ones with the rubber ring on the inside edge.

Thanks kop.

Yea i normally use hawk on the olive & valve union with very few problems.

Made sure the extensions were fully screwed in with no thread showing.
Im sure i did at least 12 turns but it is possible i might have been a bit shy on the number of turns so will make sure i do at least 14.

You got a link to those mate?
All i can find are the ones ive got or the telescopic ones which are pretty good but too short on this occasion

If it's leaking more ptfe is needed or loctite 577 (that will work 100%)

Cheers shaun.

Will persevere with ptfe or resort to 577 if i get no joy.

Are you putting the tape on the correct way.
One way seals the other way leaks.
