S-95647A161 15.1 mm ID x 28 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Superior chemical resistance prevents degradation from oils, solvents, and industrial chemicals, extending service life in harsh environments
• Excellent dimensional stability maintains precise 15.1mm ID and 28mm OD measurements under varying conditions for reliable fit and function
• Rockwell M90 hardness provides optimal balance between surface durability and impact resistance for long-term performance
• Low friction properties reduce wear on mating surfaces and minimize galvanic corrosion when used with dissimilar metals
• 180°F temperature resistance ensures consistent performance in moderate heat applications without deformation
• Lightweight construction reduces overall assembly weight while maintaining structural integrity compared to metal alternatives
• Regulatory compliance ready with RoHS 3 and REACH certification for global industrial applications and supply chain requirements

Professional Applications & Engineering Value

This M14 Delrin® Acetal Plastic Flat Washer delivers critical engineering advantages where metal fasteners fail. The Delrin® acetal material provides inherent chemical resistance against industrial solvents, fuels, and cleaning agents that typically corrode metal washers. Its low moisture absorption maintains dimensional stability in humid environments, preventing the swelling or shrinkage that compromises sealing performance. The white color offers visual contrast for inspection and meets cleanroom requirements. Engineers specify this metric flat washer for electrical enclosures, food processing equipment, marine applications, and chemical handling systems where non-conductivity, corrosion resistance, and regulatory compliance are mandatory. The 2.1-2.6mm thickness range accommodates manufacturing tolerances while providing consistent load distribution.

Specification Summary & Compliance

This metric flat washer features precise dimensional specifications with 15.1mm internal diameter, 28mm outer diameter, and 2.1-2.6mm thickness range compatible with M14 screw sizes. Manufactured from Delrin® Acetal Plastic with Rockwell M90 hardness rating, the washer maintains mechanical properties across its operational range. The product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical substances, verified through the latest SVHC assessment (06/14/2023, 235 SVHC). Temperature tolerance reaches 180°F maximum while maintaining structural integrity and performance characteristics.
