S-90467A206 5.8 mm ID x 11.3 mm OD High-Pressure Bonded Sealing Washers For Screw Heads

Key Features & Benefits at a Glance

• Exceptional sealing performance with bonded fluorocarbon rubber that prevents fluid and gas leakage under extreme pressures
• Superior temperature resilience maintaining seal integrity from 0°F to 390°F (-18°C to 199°C) in demanding thermal environments
• High-pressure containment handling up to 3600 PSI fluids and 200 PSI gases for critical industrial applications
• Corrosion-resistant construction using 304 stainless steel with Rockwell B90 hardness for long-term durability
• Optimized seal hardness with Durometer 75A fluorocarbon rubber providing perfect balance of compression and rebound
• Precision M6 compatibility with 5.8mm ID and 11.3mm OD ensuring perfect fit for metric fastener systems
• Reliable metal-to-rubber bonding creating permanent seal that won't separate under vibration or thermal cycling

Professional Applications & Engineering Value

This M6 metal bonded washer combines the structural integrity of 304 stainless steel with the exceptional sealing properties of fluorocarbon rubber to solve critical challenges in industrial environments. The metal bonded construction eliminates common failure points in gasket applications by permanently fusing the rubber seal to the metal washer, preventing separation under vibration and thermal stress. Engineered for high-temperature applications up to 390°F and extreme pressure conditions reaching 3600 PSI for fluids, this washer provides reliable performance in hydraulic systems, pneumatic equipment, and chemical processing applications where fluid containment is critical. The metric dimensions (5.8mm ID, 11.3mm OD) ensure precise compatibility with M6 fasteners while the black fluorocarbon rubber seal offers excellent resistance to oils, fuels, and chemicals commonly encountered in industrial settings.

Specification Summary & Compliance
