S-95611A155 1.625" ID x 3" OD Plastic Washers

Key Features & Benefits at a Glance

• Superior chemical resistance for reliable performance in corrosive environments where metal washers would degrade
• Excellent electrical insulation properties to prevent current leakage and ensure safe operation in electrical applications
• Consistent load distribution with precise 1.625" ID and 3" OD dimensions to protect surfaces and prevent fastener loosening
• Durable 65D durometer hardness maintains shape under pressure for long-term reliability in heavy-duty applications
• Temperature stability up to 140°F ensures consistent performance in various operating conditions
• Environmental compliance with RoHS 3 and REACH standards for safe use in regulated industries
• Corrosion-free performance in moisture-rich environments where metal components would typically fail

Professional Applications & Engineering Value

This PVC plastic flat washer delivers exceptional engineering value in applications where chemical resistance and electrical insulation are critical. The gray PVC material provides inherent protection against corrosive chemicals, acids, and solvents that would rapidly deteriorate metal washers. With its 1.625" ID precisely matching 1 1/2" screw size requirements and generous 3" OD, it effectively distributes clamping force across a wider surface area, preventing material deformation and maintaining joint integrity. The Durometer 65D hardness ensures the washer maintains its structural integrity under sustained pressure, while the 0.112-0.139" thickness provides optimal compression characteristics. These industrial plastic washers are particularly valuable in electrical enclosures, chemical processing equipment, marine environments, and plumbing systems where both corrosion resistance and electrical isolation are essential for system reliability and safety.

Specification Summary & Compliance

This flat washer features precise dimensional specifications including 1.625" inner diameter, 3" outer diameter, and 0.112-0.139" thickness range, designed specifically for 1 1/2" screw applications in the inch measurement system. The PVC plastic construction delivers Durometer 65D hardness with a maximum operating temperature of 140°F. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
