- Wide temperature tolerance from -30°F to 220°F, maintaining seal integrity in extreme thermal environments
- Enhanced corrosion protection through zinc-plated steel construction, extending service life in harsh industrial conditions
- Optimized dimensional compatibility with 1.02" ID and 1.75" OD, ensuring perfect fit for 1" screw applications
- Reliable mechanical strength with Rockwell B71 hardness, providing durable load distribution and vibration resistance
- Regulatory compliance assurance meeting RoHS 3 and REACH standards, suitable for global industrial supply chains
Professional Applications & Engineering Value
This metal bonded washer combines zinc-plated steel structural integrity with Buna-N rubber seal flexibility to solve critical sealing challenges in industrial equipment. The 1.02" ID x 1.75" OD dimensions provide precise alignment for 1" screw fastening systems, while the Durometer 55A seal hardness ensures optimal compression without deformation. Engineers specify this solution for hydraulic systems, pump assemblies, and heavy machinery where 5000 psi fluid pressure resistance and temperature extremes from -30°F to 220°F would compromise standard washers. The black seal offers UV resistance and visual inspection clarity, making it ideal for outdoor industrial applications and maintenance-critical environments.
Specification Summary & Compliance
Manufactured to inch system standards with precise 1.02" inner diameter and 1.75" outer diameter tolerances. The metal bonded construction features Rockwell B71 hardness steel base with 0.115-0.125" thickness consistency. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and chemical substance restrictions adherence for industrial distribution.
