S-90467A141 0.988" ID x 1.76" OD High-Pressure Bonded Sealing Washers For Screw Heads

Key Features & Benefits at a Glance

• Superior sealing performance with a bonded fluorocarbon rubber seal that prevents fluid and gas leaks under extreme pressures up to 3200 psi for fluids and 200 psi for gases.
• Exceptional corrosion resistance due to 304 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Wide temperature tolerance from 0°F to 390°F, maintaining seal integrity and mechanical properties across diverse operating conditions.
• Optimized mechanical strength with Rockwell B90 hardness, providing excellent load distribution and resistance to deformation under high stress.
• Precision dimensional fit with 0.988" ID and 1.76" OD designed specifically for 1" screw applications, ensuring easy installation and secure fastening.
• Durable elastomer performance featuring a Durometer 75A fluorocarbon rubber seal that offers consistent flexibility and wear resistance.
• Reliable bonded interface where metal and rubber are permanently fused, eliminating seal displacement and enhancing assembly longevity.

Professional Applications & Engineering Value

This 304 stainless steel metal bonded washer is engineered to address critical sealing challenges in demanding industrial applications. The metal bonded design permanently integrates a black fluorocarbon rubber seal with the stainless steel washer, preventing common failures like seal extrusion or loosening under vibration. It effectively solves leakage issues in hydraulic systems, pneumatic equipment, and high-pressure fluid handling assemblies where temperatures fluctuate between 0°F and 390°F. The combination of Rockwell B90 hardness for the metal component and Durometer 75A for the seal ensures balanced compression and resilience, making it ideal for 1" screw size installations in machinery, automotive, and processing industries. This design delivers consistent performance, reduces maintenance downtime, and enhances the safety of pressurized systems.

Specification Summary & Compliance

The washer meets precision dimensional standards with an ID of 0.988", OD of 1.76", and thickness between 0.059" and 0.069" for reliable fit in inch system applications. It conforms to industry practices for metal bonded washers and is manufactured using 304 stainless steel and fluorocarbon rubber materials. The product is designed to support compliance with common industrial requirements for pressure and temperature ratings, though specific standard references (e.g., ASME) should be verified per application. Materials used are generally consistent with RoHS and REACH directives for restricted substances.
