S-95630A212 0.25" ID x 0.665" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional high-temperature performance - withstands continuous operation up to 500°F, ideal for demanding thermal environments
• Superior chemical resistance - PTFE material provides excellent protection against corrosive substances and harsh industrial chemicals
• Precise dimensional fit - 0.25" ID and 0.665" OD ensure perfect alignment with No. 12 screws, preventing loosening and misalignment
• Optimal hardness and durability - Durometer 55D rating delivers reliable load distribution while maintaining flexibility for vibration resistance
• Consistent thickness control - 0.193-0.203" thickness range guarantees uniform pressure distribution and reliable sealing performance
• Regulatory compliance assurance - Meets RoHS 3 and REACH standards for safe use in regulated industrial applications
• Low friction surface - PTFE's natural lubricity reduces wear on mating surfaces and facilitates easier assembly/disassembly

Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical engineering solutions where standard metal washers fail. The white PTFE material provides exceptional chemical inertness, making them ideal for chemical processing, pharmaceutical, and food industry applications where corrosion resistance is paramount. The 500°F maximum temperature rating ensures reliable performance in high-heat environments such as oven assemblies, automotive systems, and industrial equipment. The precise 0.25" ID and 0.665" OD dimensions, combined with controlled thickness, prevent galvanic corrosion when used with No. 12 screws in mixed-material assemblies. Their Durometer 55D hardness provides the perfect balance between compression resistance and sealing capability, solving common issues of material creep and bolt loosening in vibrating machinery.
