The ALLSTAR PERFORMANCE Crush Washers 3/8in-10mm 10-pack (ALL50082) is an essential fastener solution for engine builders, transmission technicians, and automotive enthusiasts performing hydraulic system work, fuel system installations, and brake line assemblies. Crush washers serve a critical sealing function in any application requiring a metal-to-metal sealed connection, preventing fluid leakage at high pressures and temperatures.
These washers function by deforming under bolt torque to fill microscopic surface irregularities and create a permanent seal between two metal faces. The 3/8-inch size is commonly used in various applications, but it is important to note that it is not an exact match to 10mm, which could lead to compatibility issues. ALLSTAR PERFORMANCE's crush washers are typically made from soft aluminum, chosen for its ability to plastically deform without cracking while providing reliable sealing across repeated thermal cycles.
Having quality crush washers on hand eliminates the frustration of mid-project fluid weeping and costly comebacks. The 10-pack quantity ensures you have sufficient spares for a complete system assembly, modifications, or to maintain an organized shop inventory for recurring maintenance and custom builds. Mechanics and engine builders will find these washers invaluable for ensuring leak-free connections in their projects.
