Professional Applications & Engineering Value

This 316 stainless steel metal bonded washer is engineered to address critical sealing challenges in demanding industrial applications. The combination of a robust metal core and a resilient black PVC plastic sealant creates a reliable barrier against high-pressure fluids and gases, preventing leaks in systems such as hydraulic assemblies, chemical processing equipment, and offshore installations. Its temperature resistance from -60°F to 270°F ensures operational integrity in fluctuating environments, while the Rockwell B77 hardness provides excellent mechanical strength to withstand vibration and compressive loads. By integrating a bonded seal design, it eliminates the need for separate gaskets, simplifying installation and reducing maintenance downtime in heavy-duty washers applications.
