I need a red rubber washer for the bottom of an unidentified tub valve cartrige. Here is a photo of the cartrige and the broken rubber washer (gasket)

The red rubber washer is broken and I think all I need is that. All else seems OK. Can anyone help me ID the cartrige (or washer?)

When it starts leaking it's more than the washer. Its actually the ceramics inside the cartridge. You would need to replace the part itself .

Do you have a picture of the unit ?/ fixture ?

Yes, can you see the 2 photos attached to the orig post? In this case it was unused for years and stuck shut, forcing it on broke the washer but the inside seems tight (I hope?). The spline has 20 points and measures .302 inches outside dia.

"Fixture" would be the faucet. Your photos show the cartridge.
