Professional Applications & Engineering Value

Engineered for demanding food industry applications, this silicone rubber flat washer addresses critical challenges like thermal expansion, chemical exposure, and sanitary compliance. Its FDA-compliant formulation prevents leaching, while the wide temperature range from -80°F to 450°F ensures stability in sterilization processes or freezing operations. The Durometer 60A hardness balances pliability and load distribution, creating reliable seals on M10 screws in machinery, conveyor systems, and processing equipment. By resisting common industrial cleaners and maintaining integrity under cyclic stress, it reduces downtime and replacement costs, making it an essential metric washer for high-temperature and chemical-resistant sealing solutions.

Specification Summary & Compliance

This washer meets precise dimensional standards with an Inner Diameter of 10.5 mm, Outer Diameter of 20 mm, and Thickness range of 1.320mm–1.820mm, designed for M10 screw size. It conforms to FDA 21 CFR 177.2600 for food contact, RoHS 3 (2015/863/EU) for restricted substances, and REACH (EC 1907/2006) for chemical safety, ensuring full regulatory adherence in industrial use.
