Professional Applications & Engineering Value

These FDA-compliant silicone rubber flat washers deliver critical sealing solutions where thermal stability and food-grade certification are paramount. The silicone rubber material maintains elasticity across extreme temperature fluctuations (-100°F to 450°F), preventing brittle failure in freezer applications or softening in high-temperature sterilization processes. Engineered specifically for food industry applications, these washers resist degradation from steam, cleaning chemicals, and food oils while meeting strict hygiene standards. The 0.355" ID provides precise alignment with 3/8" screws, creating reliable seals in processing equipment, commercial ovens, and food packaging machinery where contamination risks must be eliminated. The flat washer design distributes clamping force evenly, protecting delicate surfaces while maintaining consistent sealing pressure through thermal expansion cycles.

Specification Summary & Compliance

This flat washer features inch system dimensions with 0.355" inner diameter and 0.812" outer diameter, designed specifically for 3/8" screw applications. Manufacturing complies with FDA 21 CFR 177.2600 for food contact surfaces, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) for chemical safety. The 60A durometer silicone rubber maintains consistent performance across the specified thickness range of 0.083-0.103", ensuring reliable sealing in demanding industrial environments.
