Forced Performance 18mm Aluminum Crush Washer

When you're working on fabricating custom fluid lines or replacing a fitting on your engine, a good seal is critical. This 18mm aluminum crush washer from Forced Performance is designed to create a reliable seal between a fitting and a surface, preventing leaks in your oil, coolant, or fuel systems. Its aluminum construction is lightweight and conforms well to mating surfaces under pressure.

This washer is a simple but essential component for any custom fabrication project or repair where a leak-free connection is needed. It's designed to crush slightly when tightened, forming a tight barrier against leaks. Always ensure you have the correct size washer for your specific fitting to achieve the best possible seal.
