M6–M16 Sump Plug Gasket — Combined Sealing Washer Bonded Seal Oil Resistant O-Ring Combination Gasket for Car

M6–M16 Sump Plug Gasket — Combined Sealing Washer Bonded Seal Oil-Resistant O-Ring Combination Gasket

Combined sealing washers (bonded seal / Dowty seal) for engine sump plug and oil drain plug sealing. The bonded seal combines a metal washer with a vulcanized rubber O-ring on the inner face — the rubber compresses against the oil pan surface when tightened, creating a superior oil-resistant seal compared to plain aluminum crush washers. Available in M6 to M16 to cover all common drain plug thread sizes.
