Professional Applications & Engineering Value

These metal bonded washers solve critical sealing challenges in industrial environments where standard washers fail. The permanent bond between 304 stainless steel and fluorocarbon rubber creates a reliable barrier against both high-pressure fluids (4400 PSI) and gases (200 PSI), eliminating leakage points in hydraulic systems, pneumatic controls, and chemical processing equipment. The black fluorocarbon rubber seal maintains flexibility across a wide temperature range (-0°F to 390°F), while the Rockwell B90 hardness provides structural support that prevents crushing under bolt torque. Engineered for No. 8 screws with precise inch-system dimensions, these washers deliver consistent performance in automotive, aerospace, and manufacturing applications where vibration resistance and long-term sealing are paramount.
