• Consistent performance with Durometer 55D hardness providing optimal compression resistance and durability under load
• Precise fit for 3/8" screws with 0.406" ID and 1" OD dimensions, ensuring secure fastening and even load distribution
• RoHS 3 and REACH compliance guarantees safety and environmental responsibility for regulated industrial sectors
• Low maintenance and long service life thanks to PTFE's inherent wear resistance and non-stick properties

Professional Applications & Engineering Value

This PTFE plastic flat washer is engineered to address critical challenges in industrial settings where standard metal washers fail. Its white PTFE material offers outstanding chemical resistance, making it ideal for chemical processing, pharmaceutical, and food equipment where exposure to aggressive substances is common. The high-temperature capability up to 500°F ensures reliable performance in HVAC systems, automotive assemblies, and industrial machinery operating under thermal stress. The flat washer design combined with PTFE's natural lubricity provides excellent sealing and insulation, preventing fluid leakage and electrical conductivity in plumbing, electrical enclosures, and precision instrumentation. With its 3/8" screw size compatibility and consistent dimensions, it delivers uniform clamping force and vibration resistance, reducing maintenance downtime and enhancing operational safety in industrial washers applications.
