Designed for professional mechanics, automotive technicians, and DIY enthusiasts, these Van Line copper washers provide a robust, leak-resistant seal for high-pressure and high-temperature applications. They are an essential workshop consumable for maintaining fluid systems, though users should ensure they are not reused after initial compression to maintain optimal integrity.

It is generally not recommended to reuse copper washers. Once tightened, the metal is compressed and deformed to create the seal. Reusing it may compromise the integrity of the seal.
Yes, these are commonly used for banjo fittings in automotive brake and hydraulic systems where high pressure is present.
The inner diameter should match your bolt shank size (1/2 inch or 12mm) to ensure it fits snugly without obstruction.
Typically, no. The copper washer is designed to act as the primary gasket and should form a seal on its own when properly torqued.
Copper is compatible with most automotive fluids, including engine oil, transmission fluid, and brake fluid.
Verify the mating surfaces are flat and free of debris. Ensure the bolt was torqued to the correct specification.
Check that the fastener size is exactly M12 (1/2 inch). A mismatched washer will not center correctly.
To achieve the best results, ensure both mating surfaces are clean and free of debris, old gasket material, or oil residue before installation. Use a torque wrench to tighten the bolt to the manufacturer's specific settings, as copper requires consistent pressure to deform correctly and seal the joint.
Compatibility: These washers are designed for use with standard 1/2 inch or M12 size fasteners. Always verify the inner diameter matches your bolt thread precisely.
Care: Store in a dry environment to prevent oxidation. Although copper naturally develops a patina, it does not affect its sealing performance. Avoid contact with incompatible chemicals that might accelerate corrosion.
