Professional Applications & Engineering Value
This hard fiber flat washer delivers exceptional engineering value in demanding industrial applications where chemical resistance and electrical insulation are critical. The gray hard fiber material maintains its structural integrity when exposed to oils, solvents, and moderate temperatures up to 230°F, making it ideal for pipeline flange connections, electrical panel assemblies, and machinery insulation points. The precise 0.75" inner diameter ensures perfect fitment for 3/4" fasteners, while the generous 2.25" outer diameter provides superior load distribution and surface protection. These industrial washers effectively prevent galvanic corrosion between dissimilar metals and maintain consistent performance in HVAC systems, chemical processing equipment, and power distribution applications where reliable sealing and isolation are paramount.
Specification Summary & Compliance
This hard fiber flat washer features precise inch system dimensions with 0.75" internal diameter, 2.25" outer diameter, and controlled thickness between 0.120-0.130". Manufactured to exacting standards for 3/4" screw size applications, the washer demonstrates Rockwell R70 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory acceptance for industrial use across global markets.
