Crush Washer Aluminum

This aluminum crush washer is a precision-engineered sealing component for Hyundai vehicle fluid systems. Designed for single-use, it ensures a hermetic seal at critical connection points like oil drain plugs. Under torque, it deforms precisely to conform to mating surfaces, eliminating micro-gaps and preventing fluid leaks. Manufactured to stringent specifications, this washer guarantees proper fitment and reliable performance, crucial for maintaining system integrity during maintenance and supporting vehicle longevity.

Technical Specifications

• Material: High-purity aluminum alloy (e.g., 1050 temper), optimized for malleability and corrosion resistance, ensuring effective cold flow under compression.
• Dimensions (ID/OD/Thickness): Precisely machined for specific bolt diameters (e.g., 14mm ID) and adequate sealing surface (e.g., 20mm OD), with calibrated thickness (e.g., 1.5-2.5mm) for controlled deformation.
• Sealing Principle: Deformation-based. Axial compression causes radial expansion, conforming the aluminum into surface irregularities of mating components for a fluid-tight barrier.
• Temperature Range: Maintains sealing efficacy from -30°C to +150°C, ensuring integrity across diverse automotive operating conditions.
• Corrosion Resistance: Excellent resistance to oxidation and degradation from automotive fluids (oil, transmission fluid, coolants), enhancing long-term seal reliability.
• Manufacturing: Precision stamped and deburred, ensuring consistent dimensions, flatness, and absence of burrs that could compromise the seal.
