Always does the trick for me. Lsx on the threads, tighten by hand and a notch or two with a wrench - then make a circular sausage from plumbers mait to form a barrier around the exterior of the join - above the plastic nut (not on it). That way any water that does make it to the LSX (it won’t) can’t go back up and over the rim of the nut.
PTFE tape would work the same as LSX true, I prefer working with the gel than tape but either is fine really.
Interesting, thanks. I've not heard of plumbers mait before but I got most of my plumbing tips from the fitters at work who make steam/solvent pipework, so their suggestion was stag paste!
It's useful stuff, but the temptation can be to use it to temporarily bodge shoddy work so it at least works/doesn't drip. Don't ask me how I know this...
