Description
Aeroflow M12 Metric Brass Crush Washers (10 Pack)
Precision-engineered 12mm I.D. brass crush washers designed for leak-free fluid and fuel sealing in high-performance motorsport applications.
Engineered Sealing for Motorsport & Performance Fuel Systems
The Aeroflow AF181-12 metric brass crush washers are designed to provide a positive, leak-proof seal across high-pressure fuel injection systems, banjo bolt connections, and straight-thread metric fittings. Manufactured from premium malleable brass, these crush washers deform slightly under torque to conform perfectly to sealing surfaces, preventing oil, fuel, or coolant leaks in aggressive motorsport environments.
Engineered with a 12mm internal diameter and an 18mm outer diameter, the AF181-12 pack is essential for custom fuel rails, oil feed lines, turbo plumbing, and brake line banjo fittings. Aeroflow recommends replacing crush washers during every service or fitting teardown to guarantee maximum sealing integrity.
