Professional Applications & Engineering Value
This PTFE plastic flat washer delivers critical performance advantages in demanding industrial settings where conventional materials fail. The white PTFE material maintains structural integrity across extreme temperature fluctuations from cryogenic to 500°F, solving thermal expansion mismatch issues in high-temperature assemblies. Its inherent chemical resistance protects against aggressive fluids and solvents in chemical processing, petroleum, and semiconductor equipment. The low friction coefficient prevents galling and seizing in dynamic applications, while the precise 0.89" ID x 1.5" OD dimensions ensure proper load distribution for 7/8" fasteners. Meeting NAS1515-M14 specifications, this washer provides aerospace-grade reliability for critical sealing, insulation, and spacing functions across multiple industries.
Specification Summary & Compliance
This flat washer features precise inch system dimensions with 0.89" inner diameter, 1.5" outer diameter, and thickness ranging 0.057-0.075". Manufactured to NAS1515-M14 specifications for consistent quality and dimensional accuracy. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in global markets. Designed specifically for 7/8" screw applications with exceptional temperature stability up to 500°F.
