Glowshift's Replacement Oil Filter O-Ring Gasket was created to replace the existing O-Ring being used in either an oil filter adapter or oil cooler sandwich adapter. An engine oil filter adapter gasket keeps engine oil from leaking out of the adapter, and it can require replacement periodically since it wears out over time. This oil filter gasket is offered in two different sizes. You can select a diameter of 2-9/16” (66mm) or a larger gasket that features a diameter of 3-3/4” (96mm) or 4-1/16" (100mm). Please use the list below to verify which oil filter housing gasket style is needed for your oil filter or oil cooler sandwich adapter. GlowShift includes free lifetime tech support and a one-year limited warranty with each purchase.
