Hi BSA500,
PRV washer 27mm o/d 22mm I/d and any thickness. Excuse the funny measurement but I can't do imperial anymore.

Thanks muskrat,
I suppose I need to pin that up in the garage as a quick reference.

The thickness of the outside fibre washer affects the PRV opening pressure
(can't remember which is big and small ???)

I printed these two charts out as A3 and had them laminated and stuck them up on the wall of my shed above my lathe, very handy.
