Vibrant 20946 M18 Copper Crush Washers - Pack of 10

The Vibrant Performance M18 Copper Crush Washers are essential sealing components designed for high-performance automotive applications. These washers are specifically sized for M18 bolts and fittings, commonly used with oil drain plugs, turbo oil feed lines, and other critical fluid connections.

Key Features:

• M18 size fits standard metric bolts and drain plugs
• Copper construction provides superior sealing and heat resistance
• Designed to deform (crush) upon installation to create leak-free seal
• Single-use washers ensure optimal sealing performance
• Prevents overtightening damage to aluminum pans and housings
• Package of 10 washers for multiple oil changes or installations

Crush washers are designed to be replaced each time a fitting is removed and reinstalled. The soft copper material compresses to fill microscopic imperfections in mating surfaces, creating a reliable seal that prevents oil and fluid leaks. Ideal for performance builds, turbo installations, and routine maintenance on high-performance vehicles.
