Professional Applications & Engineering Value

This high-temperature flat washer combines Aramid Fabric reinforcement with Buna-N Rubber to create an engineered solution for demanding industrial applications. The composite material structure delivers excellent vibration isolation and thermal insulation properties while maintaining dimensional stability under extreme thermal cycling from 0°F to 450°F. Ideal for heavy-duty equipment, industrial machinery, and high-temperature assembly applications, this washer provides reliable sealing and load distribution for 7/8" screw installations where conventional washers would fail. The fabric-rubber construction effectively resists compression set and maintains sealing integrity in challenging environments where thermal expansion and mechanical stress are constant concerns.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.938" inner diameter and 2.25" outer diameter, this flat washer features a controlled thickness range of 0.115-0.135" for consistent performance. The washer complies with RoHS 3 (2015/863/EU) requirements and meets REACH (EC 1907/2006) compliance standards as of June 14, 2023. Engineered for use with 7/8" screws in inch system applications, this component maintains structural integrity across the specified temperature range while providing reliable service in industrial fastening systems.
