Professional Applications & Engineering Value

This metal bonded washer combines the structural strength of 18-8 stainless steel with the flexibility of a neoprene rubber seal to address common industrial challenges like fluid ingress, vibration loosening, and thermal expansion. The black neoprene seal (Durometer 65A) provides consistent compression recovery, making it ideal for industrial applications in automotive, machinery, and outdoor equipment where corrosion resistance and temperature fluctuations are concerns. Its bonded design ensures the seal remains securely in place, eliminating the need for separate gaskets and simplifying assembly in high-performance sealing systems.
