S-90467A132 0.301" ID x 0.603" 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 leaks under extreme pressures up to 3700 psi for fluids and 200 psi for gases.
• Superior temperature resistance allows reliable operation in environments ranging from 0°F to 390°F, ideal for industrial applications with thermal cycling.
• Durable 304 Stainless Steel construction provides excellent corrosion resistance and structural integrity, ensuring long service life in harsh conditions.
• Precise dimensional fit with 0.301" ID and 0.603" OD designed for 5/16" screws, offering secure fastening and reduced installation errors.
• Optimized material hardness featuring Rockwell B90 for the metal and Durometer 75A for the seal, balancing mechanical strength with flexible sealing.
• Robust metal-to-rubber bonding enhances seal stability and prevents separation under vibration or pressure fluctuations.
• Versatile inch system compatibility ensures easy integration into standard industrial equipment and maintenance workflows.

Professional Applications & Engineering Value

This metal bonded washer combines 304 Stainless Steel with a Fluorocarbon Rubber seal to address critical challenges in high-pressure and temperature-sensitive environments. Engineered for applications such as hydraulic systems, pneumatic controls, and chemical processing equipment, the washer effectively seals against fluids and gases, preventing leaks that can lead to downtime or safety hazards. The black Fluorocarbon Rubber offers excellent resistance to oils, fuels, and chemicals, while the stainless steel base maintains dimensional stability and corrosion resistance. By integrating a bonded design, it eliminates the need for separate gaskets, simplifying assembly and reducing the risk of seal failure in industrial washers used in demanding sectors like automotive, aerospace, and manufacturing.
