S-95630A561 5.3 mm ID x 9 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Extreme temperature resilience from -50°F to 500°F for reliable performance in both cryogenic and high-heat environments
• Superior chemical resistance due to PTFE material, preventing degradation from harsh industrial chemicals and solvents
• Consistent dimensional stability with precise 5.3mm ID and 9mm OD metric sizing for perfect M5 screw compatibility
• Optimized load distribution through 0.9-1.1mm thickness and Durometer 51D hardness for vibration dampening and surface protection
• Regulatory compliance assurance with RoHS 3 (2015/863/EU) certification for safe use in regulated industries
• Non-corrosive and non-conductive properties making it ideal for electrical and chemical processing applications
• Minimal maintenance requirements thanks to PTFE's low friction and self-lubricating characteristics

Professional Applications & Engineering Value

This PTFE plastic flat washer delivers critical engineering solutions where temperature extremes and chemical exposure compromise conventional metal washers. The M5 metric sizing with precise 5.3mm internal diameter ensures perfect fitment with standard fasteners, while the white PTFE construction maintains integrity from -50°F to 500°F – eliminating thermal expansion concerns in automotive, aerospace, and industrial heating systems. The material's inherent chemical resistance prevents swelling or degradation when exposed to aggressive solvents, acids, and bases, making these flat washers indispensable in chemical processing equipment, pharmaceutical manufacturing, and food processing machinery where contamination must be avoided. The combination of Durometer 51D hardness and controlled 0.9-1.1mm thickness provides optimal compression resistance without sacrificing sealing capability.
