Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical engineering solutions where conventional washers fail. The PTFE material provides unmatched chemical resistance against aggressive solvents, acids, and bases, making them ideal for chemical processing equipment, laboratory instruments, and pharmaceutical manufacturing. Their 500°F temperature rating ensures stable performance in high-temperature applications such as oven assemblies, automotive engines, and industrial heating systems. The white PTFE construction offers excellent dielectric properties for electrical insulation in power distribution components. With precise 1" OD x 0.25" ID dimensions for No. 12 screws, these flat washers create reliable seals in piping systems, prevent fluid leakage in hydraulic applications, and maintain bolt tension in vibrating machinery. The Durometer 55D hardness provides the perfect balance between flexibility for sealing and rigidity for load distribution.

Specification Summary & Compliance

These PTFE plastic flat washers feature precise inch system dimensions with 1" outer diameter, 0.25" inner diameter, and thickness between 0.057-0.067". Manufactured to exacting standards for No. 12 screw applications, they maintain dimensional stability across the operating temperature range. The washers are fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards, including the latest SVHC requirements as of June 14, 2023. The Durometer 55D hardness ensures consistent performance under compression loads while the PTFE material maintains its properties from cryogenic temperatures up to the maximum rated 500°F.
