Copper Crush Washer – 8 mm ID × 13 mm OD

The 4LifetimeLines® Copper Crush Washer (8 mm ID × 13 mm OD) delivers a precision seal for brake calipers, banjo fittings, and hydraulic connections. Manufactured from high-purity copper, this washer deforms under torque to fill surface imperfections, creating a permanent, leak-proof joint critical to safe braking performance.

Key Benefits

Exact Dimensions: 8 mm inner diameter and 13 mm outer diameter for a snug, reliable fit.

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

Excellent Heat Conductivity: Rapidly dissipates heat from caliper fittings to maintain consistent hydraulic pressure.

One-Time Crush Seal: Deforms under specified torque to fill micro-gaps, ensuring a leak-free connection.

Durable & Reusable: Maintains sealing integrity through multiple service intervals when re-crushed to spec.

Installation & Usage

Clean Mating Surfaces: Remove old gasket and debris.

Position Washer: Slide the copper washer onto your banjo or caliper fitting.

Torque to Spec: Tighten the bolt to manufacturer-recommended torque—washer will compress and seal.

Inspect for Leaks: After bleeding, verify zero fluid seepage under operating pressure.
