Engine Oil Drain Plug Gasket Washer (87-91 Jeep Wrangler YJ)Find parts that fit my vehicle

Essential Seal for Oil System Integrity. This drain plug washer creates a leak-proof seal between the oil pan and drain plug, preventing seepage and ensuring proper crankcase pressure. The copper core provides excellent malleability to form around the plug threads, while the steel outer layer maintains compressive strength under high torque and temperature fluctuations. Regular replacement of this washer during oil changes is critical to avoid low-grade leaks that could lead to engine damage.

Engineered to OEM Standards. Manufactured to match Jeep’s factory specifications, the washer’s outer diameter and thickness allow it to fully compress and seal without crushing or extruding under normal service torque. Its plated finish resists rust and chemical attack from oil, coolant, and road salts, ensuring consistent sealing performance throughout its service interval.

Installation. During an oil change, remove the drain plug, discard the old washer, place the new gasket on the plug threads, tighten the plug to the manufacturer’s torque spec, and verify there are no leaks when the engine is run.

Application. The Engine Oil Drain Plug Gasket Washer fits 1987–1991 Jeep Wrangler YJ models using the factory engine oil pan drain plug.
