S-95630A350 37 mm ID x 66 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional temperature resistance up to 500°F (260°C) for reliable performance in high-heat industrial environments
• Superior chemical inertness with PTFE material that resists corrosive substances, extending equipment lifespan
• Precise metric sizing (37mm ID x 66mm OD) ensures perfect fit for M36 fasteners, preventing loosening and misalignment
• Optimal hardness (Durometer 51D) provides excellent load distribution while maintaining flexibility for vibration dampening
• Regulatory compliance with RoHS 3 and REACH standards guarantees safe use in sensitive applications
• Low friction surface reduces wear on mating components and facilitates easier assembly/disassembly
• Non-conductive properties make ideal for electrical insulation applications where metal washers would fail

Professional Applications & Engineering Value

This PTFE flat washer delivers critical performance advantages in demanding industrial settings where conventional washers fail. The white PTFE material offers unparalleled chemical resistance, making it indispensable in chemical processing, pharmaceutical manufacturing, and food processing equipment where exposure to aggressive substances is common. The 500°F temperature rating ensures reliability in high-temperature applications such as oven assemblies, heat exchangers, and automotive systems. The metric dimensions (37mm ID x 66mm OD) provide precise compatibility with M36 fasteners, while the controlled thickness (1.4-1.8mm) maintains consistent sealing and load distribution. Engineering teams specify this plastic flat washer to solve corrosion-related failures, reduce maintenance downtime, and extend equipment service life in harsh operating conditions.
