• Broad operational temperature range from 5°F to 390°F, ensuring seal integrity and mechanical performance in both hot and cold processes.
• Full compliance with food safety standards including FDA 21 CFR 177.2600, making it safe for direct and indirect food contact applications.
• Enhanced durability and secure bonding through the metal-to-rubber bonded design, resisting separation under vibration and pressure.
• Global regulatory adherence with RoHS 3 and REACH compliance, ensuring unrestricted use in international markets and responsible material sourcing.
• Optimized for M6 screw size with precise 6.1mm ID and 13.1mm OD dimensions for a perfect fit and effective load distribution.

Professional Applications & Engineering Value

This M6 metal bonded washer is engineered to solve critical challenges in sanitary and food industry applications. The core 316 stainless steel body provides superior resistance to corrosive cleaning agents and oxidation, while the permanently bonded fluoroprene fluoroelastomer seal (color-coded blue for easy identification) ensures a leak-proof barrier against moisture, grease, and microbial ingress. This combination directly addresses the engineering need for components that can withstand rigorous hygiene protocols without degrading. Its ability to maintain a Durometer 75A seal hardness across a wide temperature range from 5°F to 390°F makes it indispensable for equipment used in cooking, freezing, and pasteurization lines, preventing downtime and ensuring continuous, safe production.
