S-95630A370 43 mm ID x 78 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional thermal stability - withstands continuous exposure up to 500°F (260°C) for reliable performance in high-temperature industrial environments
• Superior chemical resistance - PTFE construction provides excellent protection against corrosive substances and harsh operating conditions
• Optimal load distribution - precisely engineered 43mm ID x 78mm OD dimensions ensure even pressure distribution for M42 screw applications
• Consistent mechanical performance - Durometer 51D hardness maintains dimensional stability and prevents deformation under compression
• Regulatory compliance assurance - meets RoHS 3 and REACH standards for safe use in regulated industries and international markets
• Low friction surface - PTFE material reduces wear on mating surfaces and minimizes torque requirements during installation
• Reliable sealing properties - 1.4-1.8mm thickness provides effective gasketing while maintaining structural integrity

Professional Applications & Engineering Value

This M42 PTFE flat washer delivers critical performance advantages in demanding industrial applications where temperature extremes and chemical exposure compromise conventional washers. The white PTFE plastic construction offers inherent chemical resistance that prevents degradation in aggressive environments, while the 500°F temperature resistance ensures reliable operation in high-heat processes. Engineered specifically for M42 screw applications, this metric washer provides superior load distribution and vibration dampening in machinery, chemical processing equipment, and high-temperature manufacturing systems. The material's low coefficient of friction reduces galling and seizing, extending component life in repetitive assembly operations.

Specification Summary & Compliance
