Copper Washer, 15mm ID, 22mm OD

The 4LifetimeLines® Copper Crush Washer (15 mm inner diameter, 22 mm outer diameter) provides a precision-engineered seal for banjo bolts, caliper fittings, and hydraulic connections. Crafted from high-purity copper, this washer deforms under torque to fill microscopic surface imperfections, creating a permanent, leak-proof joint essential for safe and consistent system performance.

Key Benefits

Precision Fit: 15 mm ID ensures a snug fit on banjo bolt shanks; 22 mm OD covers the mating surface completely.

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

Heat Dissipation: Excellent thermal conductivity maintains stable hydraulic pressure by carrying heat away from fittings.

One-Time Crush Seal: Washer compresses under the specified torque to eliminate micro-gaps—no additional sealants required.

Service-Ready: Replace the washer at every service interval to guarantee ongoing, leak-free performance.

Installation & Usage

Clean Mating Surfaces: Remove any old gasket material, debris, and corrosion from both bolt face and fitting.

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

Torque to Specification: Tighten the bolt to the manufacturer’s recommended torque; the washer will crush and conform to create a tight seal.

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