S-91367A942 0.12" ID x 0.375" OD Rubber Sealing Washers

Key Features & Benefits at a Glance

• Exceptional temperature resilience maintains sealing integrity from -60°F to 400°F, preventing leaks in extreme thermal cycling environments.
• Superior chemical resistance with fluorosilicone rubber material ensures long-term durability against oils, fuels, and solvents.
• Optimized 60A durometer hardness provides reliable compression and vibration damping without permanent deformation.
• Precision dimensional control (0.12" ID, 0.375" OD) guarantees perfect fitment for No. 6 screws and uniform load distribution.
• Regulatory compliance assurance with RoHS 3 and REACH standards eliminates supply chain compliance risks.
• High-visibility blue coloration enables quick visual inspection and inventory management in complex assemblies.
• Consistent thickness tolerance (0.083-0.103") ensures predictable sealing performance across production batches.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, this fluorosilicone rubber flat washer solves critical sealing challenges where conventional elastomers fail. The specialized polymer formulation delivers unmatched performance in automotive engine compartments, aerospace systems, and chemical processing equipment exposed to aggressive fluids and extreme temperature fluctuations. Its precision inch-dimensions and consistent 60A durometer rating create reliable anti-vibration barriers while maintaining compression set resistance. The flat washer design ensures uniform pressure distribution across No. 6 screw fastening points, preventing gasket creep in high-pressure assemblies. This combination of material excellence and dimensional accuracy makes it the engineered sealing solution for OEMs requiring long-term reliability in harsh operating conditions.
