Professional Applications & Engineering Value

This ceramic flat washer solves critical engineering challenges in extreme temperature applications where conventional metal washers would rapidly deteriorate. The off-white ceramic material provides exceptional thermal resistance while maintaining structural integrity under continuous exposure to temperatures reaching 3000°F. In industrial settings such as furnace systems, power generation equipment, and high-temperature processing machinery, this high-temperature washer prevents thermal transfer, resists chemical corrosion, and ensures reliable fastening performance. The precise 1.062" ID and 2.5" OD dimensions, combined with the flat washer design, distribute clamping forces evenly while providing essential electrical insulation. Engineered for industrial applications requiring both thermal management and mechanical reliability, this component delivers long-term value in demanding environments where failure is not an option.

Specification Summary & Compliance

This ceramic flat washer features precise dimensional specifications including 1.062" inner diameter, 2.5" outer diameter, and thickness ranging from 0.146" to 0.174" for compatibility with 1" screw sizes.
