• Optimized pressure handling withstanding up to 3600 PSI for fluids and 200 PSI for gases, ideal for demanding hydraulic and pneumatic systems
• Precise dimensional compatibility with 0.615" ID and 1.193" OD designed specifically for 5/8" screws, ensuring perfect fit and secure fastening
• Enhanced mechanical durability featuring Rockwell B90 hardness for resistance to deformation under heavy loads
• Reliable bond strength from the metal-to-rubber construction that maintains seal integrity despite vibration and thermal cycling

Professional Applications & Engineering Value

Engineered for industrial applications where reliable sealing under extreme conditions is critical, these metal bonded washers combine the structural strength of 304 Stainless Steel with the chemical and thermal resistance of Fluorocarbon Rubber seals. The black fluorocarbon rubber provides excellent compression set resistance and maintains flexibility across the full operating temperature range (-0°F to 390°F), solving common failure points in high-pressure fluid systems and thermal cycling environments. This construction prevents leakage in hydraulic systems, pneumatic controls, and processing equipment where both corrosion resistance and reliable sealing are essential. The precise 0.615" ID and 1.193" OD dimensions ensure proper fitment for 5/8" screws, making them ideal for OEM assemblies and maintenance applications requiring consistent performance under demanding operating conditions.
