Copper Washer, 1/2" ID, 20mm OD

The 4LifetimeLines® Copper Crush Washer (1/2″ inner diameter, 20 mm outer diameter) is engineered to deliver a perfect, permanent seal on brake banjo bolts, hydraulic and fuel fittings. Made from high-purity copper, this washer deforms under proper torque to fill microscopic surface imperfections, creating a one-time, leak-proof joint essential for safe, consistent system performance.

Key Benefits

Exact Fit: 1/2″ ID accommodates standard banjo bolt shanks; 20 mm OD covers the full mating face.

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

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

One-Time Crush Seal: Compresses under specified torque to eliminate micro-gaps—no sealants needed.

Service-Ready: Replace the washer at each service interval to ensure ongoing, leak-free reliability.

Installation & Usage

Clean Surfaces: Remove old gasket material, dirt, and corrosion from both the bolt face and fitting.

Position Washer: Slide the copper washer onto the banjo bolt or fitting stud, ensuring it sits flush.

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

Verify Seal: After bleeding or pressurizing the system, inspect the joint to confirm there are no leaks.

Ready for flawless sealing?
