Professional Applications & Engineering Value
This metal bonded washer is engineered to solve critical sealing and corrosion challenges in demanding industrial applications. The combination of 316 stainless steel and a PVC plastic sealant creates a robust barrier against leaks, high pressures (up to 8500 psi), and aggressive media, making it ideal for pipelines, hydraulic systems, and chemical processing equipment. Its ability to perform across a wide temperature range from -60°F to 270°F ensures reliability in both freezing and high-heat environments. By integrating the metal and seal into a single, Rockwell B77 hardness component, it eliminates assembly errors and provides a consistent, long-lasting seal that reduces maintenance downtime and enhances operational safety in fluid and gas pressure systems.
Specification Summary & Compliance
This washer features an ID of 0.77" and OD of 1.28" with a thickness of 0.105-0.115", designed for a 3/4" screw size in the inch system of measurement. It complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances. The construction meets industry standards for dimensional accuracy and material properties, providing reliable performance in high-pressure and temperature-variant applications.
