BSP thread compound

Tim Watts · 2013-05-16T10:54:46+00:00

I know - it's been done before - but there are seeming a constant stream of new products. So what would people reccomend for parallel BSP joints (brass) that I never want to get apart again - and indeed should not be easily movable after setting? This leaves out PTFE tape/string as there's no joint lock (some of the fittings will be garden bibtaps - I hate it when you tug the hose and it starts unscrewing the tap!) The compound should be potable water compatiable and ideally (natural) gas certified, though I don't have any immediate call... So far the options seem to be: LOCTITE 572 LOCTITE 577 Threadseal XS Threadseal GP and probably more :_) Cheers Tim

hemp. Put some Boss White on the threads, wind hemp into them and join. Will never leak, plus will come undone if needed.

Sadly this is no longer permitted for potable water.

Otherwise, I agree and I know how to do it.

I think the Loctite 55 is "modern hemp+bosswhite" but it does not set. Which is good for CH pumps and immersion heaters but the opposite of my requirements.
