Professional Applications & Engineering Value

Engineered for the rigorous demands of the food industry, these neoprene rubber flat washers address critical sealing and insulation challenges. The FDA compliant material prevents chemical migration, ensuring product purity in food processing lines, packaging systems, and commercial kitchen equipment. With a temperature range of -30°F to 220°F, the washer maintains elasticity and compression recovery in both freezing and moderate heat conditions, reducing leakage risks. The Durometer 55A hardness offers sufficient firmness for secure fastening while absorbing vibrations from motors and conveyors. Its white color allows for easy visual inspection in hygiene-conscious environments, and the precise 0.438" OD and 0.195" ID dimensions ensure compatibility with No. 12 screw sizes, simplifying installation in machinery assemblies.
