Copper Crush Washer – 3/8″ ID × 5/8″ OD The 4LifetimeLines® Copper Crush Washer (3/8″ ID × 5/8″ OD) delivers a precision seal for banjo bolts, caliper fittings, and hydraulic connections in your brake system. Made from high-purity copper, this washer compresses under torque to fill surface irregularities, creating a one-time, leak-proof joint essential for safe and reliable braking performance. Key Benefits Exact Dimensions: 3/8″ inner diameter and 5/8″ outer diameter for a perfect, snug fit. Corrosion Resistance: Copper alloy withstands moisture, brake-fluid vapors, and road salt without pitting. Superior Heat Conductivity: Efficiently dissipates heat from fittings to maintain consistent hydraulic pressure. One-Time Crush Seal: Deforms under specified torque to seal micro-gaps, preventing fluid leaks. Durable Performance: Maintains sealing integrity through multiple service intervals when replaced and torqued to spec. Installation & Usage Clean Surfaces: Remove old washer material
