3/4 BSP Connection sealing

by **eastdll** » Thu Jul 16, 2009 10:57 am

I'm making up connections to a thermostatic shower valve. All connections are tapped 3/4" BSP.

I want to use 90deg elbows (3/4 x 22 mm Compression) on the hot and cold inlets but not sure how to get a good seal on the BSP thread.

Do the BSP threads need to be fully tightened? If so this leaves them pointing in the wrong direction, so I back them off a bit.

Manufacturer of the valve only says to use a proprietary thread sealer. I called them for further advice and they say plenty PTFE tape.

Do I put a load of tape wraps on the thread?

Would using a washer be advised?

Can anyone offer any further advice?

Many thanks.

PRFE tape on thread - in direction of thread, sometimes you come to apoint where you cannot get it to point in the direction you want, turning back abit doesn't normally affect the watertight seal, check for leaks before plastering/fitting bath panel etc etc - normally best to leave for a couple of days.
