Professional Applications & Engineering Value

This metal bonded washer combines the structural strength of zinc-plated steel with the sealing flexibility of Buna-N rubber to solve critical industrial challenges. The bonded design eliminates separate seal components, reducing installation time and preventing assembly errors in high-pressure hydraulic systems, pneumatic equipment, and industrial machinery. The black Buna-N seal maintains elasticity across extreme temperature fluctuations from -10°F to 240°F, preventing brittle failure in cold conditions and maintaining compression at elevated temperatures. Engineered for 1 1/4" screws, this washer provides reliable fluid containment up to 4600 PSI, making it ideal for applications where seal failure would result in costly downtime or safety hazards.

Specification Summary & Compliance

Precision manufactured to inch system dimensions with 1.229" ID and 2.01" OD, featuring a thickness range of 0.059-0.069" for consistent performance. The zinc-plated steel construction meets industry standards for corrosion resistance while the Buna-N rubber seal (Durometer 60A) complies with common industrial material specifications. The assembly demonstrates Rockwell B105 hardness for structural integrity and maintains sealing capability across the specified temperature and pressure ranges. Manufactured in compliance with relevant industrial standards for metal bonded washers and suitable for applications requiring reliable sealing performance.
