S-90130A012 0.17" ID x 0.5" OD Rubber Sealing Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance: Made from EPDM rubber to create a reliable, water-tight seal that prevents leaks in industrial assemblies.
• Excellent Vibration Dampening: Absorbs shock and reduces noise, protecting your No. 10 screw fastenings from loosening under dynamic loads.
• Wide Temperature Resilience: Maintains flexibility and sealing integrity in environments from -20°F to 212°F, ensuring performance in both cold and hot conditions.
• Consistent Dimensional Accuracy: Precise 0.17" ID and 0.5" OD with a thickness of 0.078-0.108" provides a perfect fit and uniform compression.
• Durable & Flexible Material: Durometer 65A hardness offers the ideal balance of softness for sealing and toughness for long service life.
• Environmental & Regulatory Compliance: Fully compliant with RoHS 3 and REACH standards, making them safe for use in regulated industries.
• Corrosion & Weather Resistance: EPDM material inherently resists oxidation, ozone, and weathering, ideal for outdoor or harsh applications.

Professional Applications & Engineering Value

This EPDM rubber flat washer is engineered to solve critical sealing and insulation challenges in demanding environments. Its black EPDM rubber construction provides excellent resistance to water, steam, and many chemicals, making it a top choice for plumbing, HVAC, automotive, and electrical enclosures. The flat washer design ensures even load distribution under the head of a No. 10 screw, preventing surface damage and maintaining clamp force. The material's inherent flexibility compensates for surface irregularities, creating a superior seal that prevents fluid ingress and reduces vibration-induced failures. This combination of reliable temperature resistance and robust material properties extends maintenance intervals and enhances the overall durability of your assembled components.
