Wurlitzer 4 in 1 Gasket used between the valve body and the mounting plate. Made from .020 thick blotting paper. Which is critical to achieve the correct valve travel.
Friendly advise : When rebuilding 4 in 1 valves, make sure to allow for the thickness of the gasket when recovering the valves so you have the correct valve travel. There normally is not a gasket for the top cap. The leather installed on the cap for the pouches also acts as a gasket to seal the cap.
These gaskets are sold in a pack of 15. (Price includes shipping within the US.) Additional International shipping charges will apply.
