Hi BSA500,

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

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.
