S-95630A460 0.21" ID x 0.875" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional heat resistance with a 500°F maximum temperature rating, ideal for high-temperature industrial environments
• Superior chemical resistance due to PTFE material, protecting assemblies from corrosive substances and extending service life
• Reliable sealing and insulation performance with Durometer 55D hardness, ensuring consistent compression and electrical isolation
• Precise dimensional fit with 0.875" OD and 0.21" ID, designed specifically for No. 10 screws to prevent loosening and misalignment
• Consistent thickness control between 0.017-0.023", providing uniform load distribution and vibration dampening
• Full regulatory compliance with RoHS 3 and REACH standards, ensuring safe use in regulated industrial applications
• Low friction PTFE surface reduces galling and allows for easy installation and removal in tight spaces

Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical performance in demanding environments where conventional washers fail. The PTFE material provides exceptional chemical resistance against aggressive fluids and solvents, while maintaining structural integrity at continuous temperatures up to 500°F. The flat washer design with precise 0.21" ID for No. 10 screws ensures proper fit and prevents leakage paths in sealing applications. Engineers specify these washers for electrical insulation, chemical processing equipment, food machinery, and aerospace applications where non-conductive properties and regulatory compliance are mandatory. The white color allows for easy identification and contamination detection in clean manufacturing environments.
