Description
Copper Crush Washer – 11.2 mm ID × 18 mm OD
The 4LifetimeLines® Copper Crush Washer (11.2 mm inner diameter, 18 mm outer diameter) is engineered for a perfect seal on banjo bolts, caliper fittings, and hydraulic connections. Made from high-purity copper, this washer deforms under torque to fill micro-imperfections, creating a permanent, leak-proof joint that’s essential for safe, consistent braking performance.
Key Benefits
Precision Fit: 11.2 mm ID for standard banjo bolt shanks and 18 mm OD for full sealing coverage.
