Metric Bonded Oil Drain Plug Gaskets - M6 M8 M10 M12 M14 M16 Single

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.

Realistic Field Applications

• Sump Plug Replacement: Replacing the "one-use" seals on MOD disposals vehicles during routine oil changes to prevent weeping sumps.

• Hydraulic Fittings: Sealing low-to-mid pressure hydraulic lines on recovery cranes, tail lifts, and plant machinery.

• Gearbox & Differential: Providing a secure seal for transmission drain and fill points that are subject to extreme temperature changes.

• Fuel Systems: Ideal for sealing banjo bolts and fuel filter housings where air ingress must be eliminated.
