Professional Applications & Engineering Value

This metal bonded washer integrates an 18-8 stainless steel base with a silicone rubber seal to address common industrial challenges like fluid ingress, gas leakage, and thermal expansion in machinery. Its metric dimensions (4.9 mm ID, 14 mm OD) ensure precise compatibility with M5 screws, making it ideal for automotive, aerospace, and HVAC systems where extreme temperatures and pressure fluctuations occur. The bonded design eliminates separate gaskets, reducing assembly time and potential failure points, while the high-temperature resistance and pressure handling up to 100 psi enhance reliability in pumps, valves, and enclosures. By combining metal strength with elastomer flexibility, it delivers a cost-effective solution for industrial sealing needs, minimizing downtime and maintenance costs.
