• Precision M5 metric fit with 5.1mm ID and 10.7mm OD, ensuring easy installation and secure fastening on standard screw sizes

Professional Applications & Engineering Value

Engineered for demanding sanitary and food industry settings, this metal bonded washer combines the structural integrity of 316 stainless steel with the sealing elasticity of fluoroprene fluoroelastomer rubber. The bonded design addresses common failure points in gasketing by eliminating seal shift or compression loss, which is critical in automated cleaning cycles and high-vibration machinery. Its FDA compliant and temperature-resistant properties make it suitable for food processing equipment, beverage dispensers, and pharmaceutical machinery where hygiene and thermal stability are non-negotiable. By integrating a Durometer 75A seal, the washer delivers consistent pressure distribution and leak prevention, reducing maintenance frequency and enhancing operational uptime in controlled environments.

Specification Summary & Compliance

This M5 metric washer features precise dimensions (ID: 5.1 mm, OD: 10.7 mm, Thickness: 1 mm) and is manufactured to meet FDA 21 CFR 177.2600 for food contact materials. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances. The fluoroprene seal maintains a hardness of Durometer 75A, providing optimal compressibility and recovery. Suitable for temperatures from 5°F to 390°F, this washer is designed for repeated use in sanitary applications without degradation.
