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.

Corrosion Resistance: Premium copper resists brake-fluid vapors, moisture, and road salt without pitting.

Heat Dissipation: Excellent thermal conductivity helps maintain stable hydraulic pressure.

One-Time Crush Seal: Compresses under specified torque to eliminate leaks—no additional sealants required.

Service Ready: Replace with every brake service interval for consistent, leak-free performance.

Installation & Usage

Clean Mating Surfaces: Remove residue, old gasket material, and debris.

Position the Washer: Slide the copper washer onto the banjo bolt.

Torque to Spec: Tighten the bolt to the manufacturer’s recommended torque; the washer will crush and seal.

Verify Seal: After bleeding or pressurizing, inspect the joint to ensure no fluid seepage.

Ready to lock in a perfect seal?
Add the 11.2 mm × 18 mm Copper Crush Washer to your cart now and secure every brake and hydraulic fitting with confidence.
