Professional Applications & Engineering Value

Engineered for demanding food industry applications, these silicone rubber flat washers solve critical challenges in hygiene and thermal stability. The FDA compliant material prevents chemical leaching, ensuring product purity in food processing machinery, beverage dispensers, and packaging equipment. With a wide operating range from -80°F to 450°F, they maintain seal integrity in freezing environments and high-temperature sterilization cycles. The Durometer 60A hardness provides consistent compression recovery, effectively damping vibrations and preventing loosening in M5 screw assemblies. This combination of material properties and metric precision reduces downtime and maintenance costs in industrial settings where thermal shock and sanitary compliance are paramount.

Specification Summary & Compliance

This flat washer features precise dimensions: 5.3mm inner diameter, 10mm outer diameter, and thickness ranging from 1.320mm to 1.820mm for M5 screw compatibility. Manufactured to meet FDA 21 CFR 177.2600 for food contact applications, it also complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. The silicone rubber construction maintains Durometer 60A hardness throughout the specified temperature range, ensuring consistent performance and dimensional stability in industrial environments.
