Professional Applications & Engineering Value

This silicone rubber flat washer is engineered to address critical challenges in food industry and high-temperature applications. Its FDA compliant formulation prevents chemical leaching, ensuring product purity in food processing equipment. The silicone rubber material maintains elasticity across a broad temperature range from -80°F to 450°F, preventing brittleness in freezing conditions and maintaining seal integrity in hot sterilization processes. With a Durometer 60A hardness, it provides sufficient compression for leak-proof sealing without over-stressing connected components. The precise 0.469" ID and 0.922" OD dimensions ensure proper alignment with 7/16" screw size fasteners, reducing assembly errors in conveyor systems, mixers, and packaging machinery where hygiene and thermal stability are paramount.
