• Precise metric sizing (M16) with 15.6 mm ID and 27.1 mm OD for accurate fit and consistent performance in metric assemblies
• Optimized seal hardness at Durometer 75A providing excellent compression set resistance and sealing integrity
• Versatile black seal color for easy identification and compatibility with various industrial standards

Professional Applications & Engineering Value

This M16 metal bonded washer is engineered to address critical sealing challenges in demanding industrial settings. The 304 stainless steel body offers robust structural support and corrosion resistance, while the fluorocarbon rubber seal provides reliable performance against chemicals, oils, and extreme temperatures. It effectively prevents leakage in high-pressure fluid systems (up to 3100 psi) and gas applications (200 psi), making it ideal for use in hydraulic systems, pneumatic equipment, automotive assemblies, and chemical processing plants. The metal bonded design ensures the seal remains intact under dynamic loads and vibrations, reducing maintenance needs and enhancing operational safety. With a precise metric fit and wide temperature tolerance, this washer delivers consistent performance in critical industrial washers applications where failure is not an option.
