Metal to plastic thread weeping at water filter

[sean oc]

Hi

Didn't realise an old water filter was hidden until room was ripped out. The old filter was not nice to say the least

Bought a kit like screwfix one and the adapters which were recommended .

Its all be compression fitted by previous owner as he was a handy man so I decided to get near enough same style filter to swap

Stuck on the 3/4" to 15mm adapters but they weep as its copper to a plastic thread which then screws into the filter.

I have fitted alot of Ppte tape and the in side okay but the out side weeps. Is there something better to use that ptfe

Thanks

Loctite 55 is a good alternative.

And remove all of the PTFE from the threads of the compression fittings. It is not required and looks like a bodge.

Too much ptfe tape with too much force can cause the plastic to split and leak so don`t go all gorilla on it. If you really struggle then a light smear of lsx on the tape will help.
