Professional Applications & Engineering Value

This 316 stainless steel metal bonded washer with a black PVC plastic sealant is engineered to address critical sealing challenges in demanding industrial settings. The combination of 316 stainless steel—known for its excellent corrosion resistance—and a resilient PVC seal creates a robust barrier against leaks, even under high pressures up to 8500 PSI and extreme temperatures from -60°F to 270°F. This makes it ideal for applications in oil and gas, chemical processing, and marine equipment, where failure can lead to costly downtime or safety hazards. The metal bonded design ensures the seal remains intact during vibration and thermal cycling, providing long-term reliability and reducing maintenance needs. By integrating precise dimensions for No. 8 screws and inch-based systems, it streamlines assembly in industrial machinery and pipeline fittings, delivering consistent performance where sealing integrity is non-negotiable.
