  • hi,
  • I installed a Hudson reed thermostatic shower valve and I am having issues with it leaking. See attached photos. The fitting that goes into the valve is 3/4 BSP. This is a straight thread fitting and therefore has a rubber o-ring to make the seal.
  • When I apply full pressure to the valve the o-rings pop out. The fitting that was supplied in the box does not have enough surface to grab the o-ring and hold it tight.
  • I contacted Hudson reed and there response was to use Teflon tape. That did not work. These are straight threads not tapered threads.
  • I need help. Does anyone know where I can get a 3/4 BSP to NPT brass adapter that will seal tight to this valve.
  • The fitting in question is 3/4 BSP to 1/2 NPT brass adapter.

Is this the water from the leak that you are writing about?

Some of those adapter fittings rely on a washer verses an O-ring to make a seal in the same manner as what is used on a hose connected to your outside hose bib. The tub/shower valve I have utilizes that type of fitting and uses a washer instead of an O-ring...been working fine now for over 10-years.

Reach 4, you are pointing out my pex crimp ring. Do you not like pex? If however your question was serious then no. The water is coming from the black O-ring at the fitting that threads into the shower valve.

Getting back to topic. I will remove the o-rings that were supplied and try to find a rubber washer instead.

Precisely, use a washer that should take care of you problem if not look into another fitting type, you might be using a defective fitting.

I was serious. I thought I saw a drop of water in the photo, and I did not see what I thought was water elsewhere.

When I use O-rings, I like to lube them lightly using silicone grease. I use a nitrile glove.

I got the same stupid answer from Hudson Reed when I had the same issue. There are special washers that you can buy that are specifically for this type of connection. They are metal but also have a rubber interior piece to provide a seal. Check the link below. The size is the internal pipe size.

"BSPP (British Standard Parallel Pipe) is most popular in the UK, Europe, Asia, Australia, New Zealand and South Africa. It is a parallel thread fitting that uses a bonded seal ring to do the sealing. This bonded ring seal is sandwiched in-between a shoulder on the male fitting and the face of the female fitting and is squeezed in place"
