Here at Speedflow, we have a comprehensive range of aluminium crush washers, used to seal male adapters, banjos, and plugs that screw into a hole with a flat machined surface to accept a washer.
We recommended that washers are a one use item and should be replaced when servicing fittings or components to avoid any leaks.
Available in metric and imperial sizes, individually or in packs of 10 or 100.
