Professional Applications & Engineering Value
This metal bonded washer combines the structural reliability of zinc-plated steel with the elastic sealing properties of Buna-N rubber (Durometer 55A) to solve critical industrial challenges. The bonded design eliminates separate seal components, preventing installation errors while creating a permanent barrier against fluid ingress and pressure loss. Engineers specify these washers for hydraulic systems, pneumatic equipment, and industrial machinery where high-pressure sealing and temperature stability are paramount. The black Buna-N seal maintains flexibility across extreme thermal cycles (-40°F to 225°F), while the inch-system dimensions ensure compatibility with standard 3/4" fasteners in North American industrial applications.
Specification Summary & Compliance
Precision-engineered to inch system measurements with 0.74" ID and 1.322" OD dimensions for exact fitment. Manufactured from zinc-plated steel with Rockwell B71 hardness and bonded with Buna-N rubber seal (Durometer 55A). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use.
