S-95630A904 0.812" ID x 1.375" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional chemical resistance for reliable performance in harsh industrial environments with corrosive substances
• High-temperature stability up to 500°F maintains structural integrity and prevents deformation in demanding thermal applications
• Consistent Durometer 55D hardness provides optimal load distribution and vibration damping for extended equipment life
• Precision inch dimensions (0.812" ID x 1.375" OD) ensure perfect fit with 3/4" screws and prevent loosening under stress
• RoHS 3 & REACH compliance guarantees environmental safety and regulatory acceptance for global industrial applications
• PTFE material construction offers low friction properties that reduce wear on mating surfaces and components
• Controlled thickness variation (0.090-0.112") delivers consistent sealing performance and reliable gap filling capabilities

Professional Applications & Engineering Value

These PTFE plastic flat washers solve critical engineering challenges in high-temperature industrial applications where conventional washers fail. The white PTFE material provides inherent chemical resistance against aggressive solvents, acids, and bases, making them ideal for chemical processing equipment, pharmaceutical manufacturing, and food processing machinery. Their ability to maintain dimensional stability at continuous temperatures up to 500°F prevents thermal degradation common in standard plastic washers. The precise inch dimensions and Durometer 55D hardness ensure proper load distribution in 3/4" screw assemblies, reducing stress concentration and preventing joint failure in vibrating machinery, pump systems, and high-pressure flange connections.

Specification Summary & Compliance

Manufactured to precise inch system tolerances with 0.812" inner diameter and 1.375" outer diameter specifically designed for 3/4" screw sizes. The thickness range of 0.090-0.112" ensures consistent performance across production batches. These flat washers comply with RoHS 3 (2015/863/EU) standards for hazardous substance restrictions and REACH (EC 1907/2006) regulations concerning chemical substances, making them suitable for regulated industries and international markets requiring stringent environmental compliance.
