Cap washer, rubber, 3″ diameter. Used to seal the faceplate on Standard Re-Nu or B-201 single lever shower mixers. #4 on diagram.
Standard started to use single control mixing valves in both in-wall and exposed applications back in the 1920’s. Many of these valves are still in use today, but finding rebuild parts can be extremely difficult. A few parts are still made, and occasionally we can machine parts from your samples if they aren’t available.
