S-95630A819 0.203" ID x 1" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional high-temperature resistance up to 500°F, ensuring reliable performance in demanding thermal environments without degradation
• Superior chemical resistance due to PTFE material, protecting against corrosive substances and extending component lifespan
• Consistent dimensional stability with precise 0.203" ID and 1" OD, providing secure fit and uniform load distribution for No. 10 screws
• Optimal hardness and durability with Durometer 55D rating, offering excellent wear resistance and long-term service under mechanical stress
• Full regulatory compliance with RoHS 3 and REACH standards, ensuring safety and environmental responsibility for global industrial applications
• Reliable electrical insulation properties inherent to PTFE, preventing current leakage and short circuits in electrical assemblies
• Low friction surface reducing assembly torque and preventing galling between mating surfaces

Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical engineering solutions where standard washers fail. The PTFE material provides unmatched chemical resistance against aggressive fluids, acids, and solvents, making them ideal for chemical processing equipment, laboratory instruments, and pharmaceutical manufacturing. Their ability to withstand continuous temperatures up to 500°F solves thermal management challenges in automotive, aerospace, and industrial heating systems. The white color allows for easy identification in complex assemblies, while the precise 0.203" ID x 1" OD dimensions ensure perfect compatibility with No. 10 screws in inch-system applications. These washers prevent corrosion-induced failures and maintain sealing integrity where metal washers would corrode or degrade.

Specification Summary & Compliance

This flat washer features exact dimensional specifications including 0.203" inner diameter, 1" outer diameter, and controlled thickness between 0.057-0.067" for consistent performance.
