Metric Bonded Oil Drain Plug Gaskets – Single Units (M6 to M16)
These industrial-grade bonded seals (often referred to as Dowty washers) are essential for maintaining leak-proof connections in military vehicles, heavy plant, and garage equipment. Unlike standard flat washers, these feature a high-quality rubber inner ring permanently bonded to a zinc-plated steel outer carrier. This design ensures a superior, high-pressure seal for oil pans, gearbox drain plugs, and hydraulic lines, making them the preferred choice for restoring and servicing ex-MOD Land Rovers, trucks, and stationary generators where fluid loss is not an option.
Engineering & Performance Features
-
Self-Centering Bonded Design: The internal rubber lip centers the gasket on the bolt thread, ensuring a perfect seal every time without the risk of the washer slipping during tightening.
-
High-Pressure Integrity: Engineered to withstand the significant pressures of hydraulic systems and the thermal cycling of heavy-duty engine oil pans.
-
Chemical Resistant Rubber: The sealing element is resistant to oils, lubricants, and diesel fuels, preventing degradation over long service intervals.
-
Vibration Resistant: The flexible inner seal absorbs mechanical vibration, preventing the drain plug from loosening—a critical requirement for military surplus vehicles operating off-road.
-
Corrosion Protection: The outer steel ring is treated to resist rust and road grime, ensuring the gasket remains intact in exposed chassis environments.
