This 10piece copper washer set provides reliable sealing for oil sump drains and related fittings. Made from copper, these solid gaskets offer good conformability and corrosion resistance to help prevent leaks in oil systems. Each washer measures 6x14x2 mm (inner diameter 6 mm, outer diameter 14 mm, thickness 2 mm). Ten pieces are included per pack. Key benefits Effective leak prevention: copper washers crush slightly to form a tight seal between mating surfaces in oilcontaining assemblies. Corrosion resistant: copper stands up to oil exposure and typical automotive fluids for durable performance. Easy compatibility: sized for common 6 mm inner bore, 14 mm outer diameter, 2 mm thick applications that require a copper sealing washer. Key attributes Material: Copper (solid gasket) Size: 6x14x2 mm (inner diameter 6 mm, outer diameter 14 mm, thickness 2 mm) Quantity: 10 pieces per pack Application: Sump oil seals and other sealing needs where copper washers are specified Compatibility and performance Suitable for automotive oil sump drain plugs and related fittings that require a copper seal washer. Applicable to hydraulic fittings and oil line connections where copper washers are recommended. Designed to provide a dependable seal in oilbased systems with compatible threading and seating surfaces. Installation and maintenance tips Align washer with the sealing surface and place between the plug or fitting and the mating surface. Ensure the surfaces are clean and flat; tighten to the recommended torque to achieve proper seating. Inspect washers for deformation or damage after removal; with a washer if deformed or compromised. Use cases Automotive oil sump drain plug gasket: worn or damaged seals to prevent oil leaks from the oil pan. Hydraulic line fitting seal: seal coppertometal interfaces in hydraulic hose or line assemblies. Fuel line or other fluid connections: when copper washers are specified for sealing between fittings and flanges.
