S-95630A640 5.3 mm ID x 11 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional high-temperature resistance up to 500°F, ensuring reliable performance in demanding thermal environments
• Superior chemical resistance due to PTFE material, protecting against corrosion and extending component lifespan
• Consistent dimensional accuracy with 5.3mm ID and 11mm OD for precise fit with M5 screws, reducing assembly errors
• Optimized hardness (Durometer 51D) providing excellent load distribution and vibration damping without damaging surfaces
• Compliance with RoHS 3 and REACH regulations, ensuring safe use in regulated industrial and electronic applications
• Low friction properties of PTFE plastic minimizing wear and facilitating easy maintenance in moving assemblies
• Lightweight and non-conductive design ideal for electrical insulation and weight-sensitive equipment

Professional Applications & Engineering Value

These M5 PTFE flat washers are engineered to solve critical challenges in harsh industrial settings. The PTFE plastic material offers outstanding resistance to aggressive chemicals, acids, and solvents, preventing degradation in chemical processing, pharmaceutical, and food manufacturing equipment. With a maximum temperature rating of 500°F, they maintain structural integrity in high-heat applications like automotive engines, HVAC systems, and industrial ovens where metal washers may fail. The metric dimensions (5.3x11mm) and consistent 0.9-1.1mm thickness ensure reliable sealing and spacing in precision assemblies, while the white color allows for easy identification and quality control. These washers effectively eliminate galvanic corrosion risks in mixed-material constructions and provide essential electrical insulation in electronic enclosures.
