S-90467A138 0.74" ID x 1.322" OD High-Pressure Bonded Sealing Washers For Screw Heads

Key Features & Benefits at a Glance

• Exceptional chemical and temperature resistance with 304 Stainless Steel construction and Fluorocarbon Rubber seal, ensuring reliable performance in harsh environments from 0°F to 390°F
• Superior sealing integrity under extreme pressures, handling up to 3300 psi for fluids and 200 psi for gases to prevent leaks in critical applications
• Enhanced durability and load distribution thanks to Rockwell B90 hardness and precise 0.74" ID x 1.322" OD dimensions, reducing wear on connected components
• Optimized compatibility with 3/4" screw sizes in inch measurement systems, ensuring easy installation and secure fastening in industrial assemblies
• Long-lasting seal performance with Durometer 75A rubber hardness and black fluorocarbon material, maintaining flexibility and resistance to compression set
• Reliable performance in fluctuating conditions due to the metal-bonded design, which combines structural strength with effective vibration damping

Professional Applications & Engineering Value

This metal bonded washer integrates a 304 Stainless Steel body with a Fluorocarbon Rubber seal to address common industrial challenges like fluid leakage, thermal expansion, and chemical exposure. Its robust design is ideal for high-pressure hydraulic systems, pneumatic equipment, and high-temperature machinery, where consistent sealing under 3300 psi fluid pressure and 390°F temperatures is critical. The Rockwell B90 hardness ensures the washer maintains its shape under heavy loads, while the precise 0.74" ID and 1.322" OD dimensions provide a snug fit for 3/4" screw sizes, minimizing installation errors and enhancing assembly reliability in sectors like automotive, aerospace, and heavy manufacturing.
