A crush washer, also known as a compression washer, is a thin metal or synthetic disc designed to deform under pressure. Its primary function is to create a secure seal between two mating surfaces, preventing leaks in applications like oil drain plugs, brake caliper bolts, and fuel line connections. The 12mm size is a common specification found in many vehicles, particularly those with metric fasteners.
When installing a 12mm crush washer, it's essential to understand its proper usage. The washer should be placed between the bolt head and the surface it's tightening against. As the bolt is tightened, the washer compresses, creating a tight seal while preventing over-tightening, which can damage threads or components. The deformation of the washer ensures a consistent seal, even as parts expand or contract due to temperature changes.
