Product details
These sealing washers are made from high-quality materials for use in braking, fuel and oil systems on vehicles. Their crush design forms a tight seal between the faces of the mating components, keeping fluid contained.
Banjo fittings pre-installed on braided brake and clutch line kits come with copper washers as standard. Replacing copper crush washers whenever a fitting or line is removed is recommended, to keep the seal safe and secure.
Aluminium crush washers are widely used to seal fluid joints - oil drain plugs, fuel lines and oil lines among them. Light in weight and effective against leaks, they also resist corrosion reasonably well, though copper suits highly corrosive settings better. They pair nicely with metric-threaded parts in an oil system.
Copper crush washers suit parts that face extreme heat and highly corrosive chemicals. Copper conducts heat well and is malleable, so the washer forms a tight seal even against uneven or slightly damaged mating surfaces; its resistance to chemicals makes it a strong pick wherever corrosion is a worry.
Bonded dowty seals are sometimes chosen over crush washers for better sealing performance, fewer leaks or failures, a longer working life, and stronger resistance to shock and vibration. An internal bonded rubber seal absorbs shocks and vibration, helping stop the seal loosening or failing early. That said, the right choice depends on the application - crush washers can still suit low-pressure or low-demand uses, and cost may also be a factor.
Choosing the correct washer material for the application helps prevent leaks and keep the installation safe.
