Professional Applications & Engineering Value

This EPDM rubber flat washer is engineered to address critical sealing challenges in food industry applications, where contamination prevention and material integrity are paramount. The FDA-compliant EPDM material resists moisture, steam, and various cleaning agents commonly used in food processing, ensuring a reliable seal that protects equipment and product purity. Its flat washer design and specific 0.49" ID x 1.062" OD dimensions provide a consistent, flush fit on 1/2" screw sizes, distributing clamp load evenly to prevent leaks and joint failure. The Durometer 60A hardness offers sufficient compression set resistance, maintaining the seal under vibration and thermal cycling from -50°F to 300°F. This combination of material properties and precision sizing delivers long-term reliability, reduces maintenance downtime, and supports compliance with stringent industry regulations.
