• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible industrial use

Professional Applications & Engineering Value

This metal bonded washer combines the structural integrity of zinc-plated steel with the elastic sealing properties of Buna-N rubber to solve critical fluid containment challenges. The permanent bond prevents seal displacement under vibration while the Durometer 55A hardness provides optimal compression for leak-proof connections in hydraulic systems, pneumatic equipment, and industrial machinery. Engineered for 9/16" fasteners, it creates reliable barriers against fluid ingress and pressure loss in applications ranging from manufacturing equipment to automotive assemblies. The temperature-resistant design maintains performance from arctic conditions to elevated operating temperatures, eliminating the need for multiple specialty washers across different operating environments.
