S-95647A159 13.1 mm ID x 25 mm OD Plastic Washers

Key Features & Benefits at a Glance

• Superior chemical resistance from Delrin® Acetal Plastic material protects against industrial solvents and degradation
• Excellent dimensional stability maintains precise 13.1mm ID and 25mm OD metric sizing for consistent M12 screw fitment
• Low friction surface reduces wear and prevents galling between mating surfaces
• High mechanical strength with Rockwell M90 hardness ensures reliable performance under load
• Temperature resilience up to 180°F (82°C) for stable operation in various industrial environments
• Regulatory compliance with RoHS 3 and REACH standards for global market acceptance
• Corrosion-free performance ideal for applications where metal washers would fail

Professional Applications & Engineering Value

This M12 Delrin® Acetal Plastic Flat Washer delivers exceptional engineering value in demanding industrial settings where traditional metal washers fall short. The white Delrin® acetal plastic construction provides inherent chemical resistance against oils, solvents, and various industrial fluids, eliminating corrosion concerns that plague metal components. The material's low moisture absorption and dimensional stability ensure consistent performance in humid environments, while the 2.1-2.6mm thickness range accommodates manufacturing tolerances without compromising sealing capability. These metric flat washers are particularly valuable in food processing, electrical enclosures, and chemical handling equipment where non-conductive, non-corrosive fastening solutions are essential. The combination of Rockwell M90 hardness and temperature resistance to 180°F makes them suitable for automotive, packaging machinery, and material handling applications requiring durable, maintenance-free performance.
