OEM Gasket cover for Gaz Guzler pumps (Oberdorfer).  This gasket is used on older model pumps and should be replaced any time the pump has been opened, specifically when replacing the Buna Lip Seal.  If your pump doesn’t have a gasket inside, then it will have a Viton o-ring instead.

NOTE: THIS GASKET IS DISCONTINUED AS OF 2024 – PLEASE CALL FOR ACCURATE STOCK CHECK BEFORE ORDERING.
