Professional Applications & Engineering Value

This metal bonded washer is engineered to solve sealing and corrosion challenges in demanding industrial applications. The 316 stainless steel core provides exceptional resistance to pitting and crevice corrosion, while the integrally bonded PVC plastic sealant creates a robust, leak-proof barrier without separate gaskets. It is ideal for high-pressure fluid and gas systems, such as hydraulic assemblies, chemical processing equipment, and offshore machinery, where failure is not an option. The combination of a wide temperature range and Rockwell B77 hardness ensures that the washer maintains its integrity under dynamic stresses, reducing maintenance downtime and enhancing operational safety in critical environments.

Specification Summary & Compliance

This washer features an ID of 0.51", OD of 0.99", and thickness of 0.085-0.095", designed for a 1/2" screw size in the inch measurement system. It complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances. The construction adheres to industry standards for pressure and temperature performance, supporting reliable use in industrial washers applications requiring up to 8500 psi pressure resistance.
