    Hello I have been fitting a mixer shower behind our bathroom wall. It has 4 1/2" tap female connectors for the hot and cold inlets and the shower head and hand held show. I bought 1/2" male fittings with a 15mm compression head on the other sides for all 4. I installed the male to female with PTFE tape and all was well for about an hour and now I have a very slight weep on both inlets. Am I correct in using PTFE tape for these fittings, or do I need a non hardening sealabt, or is there something else more suitable ? Many thanks

  3. I'prefer to use Loctite 55 but PTFE tape will do the job as long as you have enough of it and it's applied correctly

    I find gas PTFE does the job handsomely, it's a bit thicker so allows a bit more flexibility with amount used and still seals ok.

    Yes I'd assumed ptfe was the same thickness but it's clearly not
