Copper Crush Washer – 10 mm ID × 16 mm OD

The 4LifetimeLines® Copper Crush Washer (10 mm inner diameter, 16 mm outer diameter) delivers a precision fit for banjo bolts, caliper fittings, and hydraulic connections. Made from high-purity copper, this washer deforms under torque to fill microscopic surface irregularities, creating a one-time, permanent seal that’s essential for reliable, leak-free brake and hydraulic systems.

Key Benefits

Exact Fit: 10 mm ID accommodates standard bolt shanks, while 16 mm OD ensures complete coverage of the mating surface.

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

Superior Heat Conductivity: Rapidly dissipates heat at the fitting interface to maintain stable hydraulic pressure.

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

Service Interval Ready: Replace the washer with every brake or hydraulic service for consistent performance.

Installation & Usage

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

Position Washer: Place the copper washer onto the bolt, ensuring it sits flush against the fitting.

Torque to Spec: Tighten the bolt to the manufacturer’s recommended torque—the washer will crush and conform for a tight seal.

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

Ready for a leak-proof seal?
