Description

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.
Yes, there used to be quite a few more numbers on the below diagram.  The missing numbers were for parts that aren’t available anymore.  The diagram is from a 1934 Standard Catalog.
