• Exceptional temperature resilience from -50°F to 300°F, maintaining seal integrity and flexibility in extreme thermal cycles.
• Consistent compression and sealing due to Durometer 60A hardness, providing reliable vibration dampening and leak prevention.
• Broad regulatory acceptance including RoHS 3 and REACH compliance, meeting stringent international safety and environmental standards.
• Precision metric fit with 5.3mm ID and 10mm OD, ensuring easy installation and secure seating on M5 screws without slippage.
• Durable EPDM rubber construction offering excellent resistance to weathering, oxidation, and common industrial cleaning agents.

Professional Applications & Engineering Value

These EPDM rubber flat washers are engineered to address critical sealing and insulation challenges in food industry equipment, commercial appliances, and sanitary processing systems. The FDA-compliant white EPDM material prevents contamination and withstands repeated sterilization, while the flat washer design ensures uniform load distribution under M5 fasteners. With a temperature range from -50°F to 300°F, they eliminate failures caused by thermal expansion or freezing conditions, reducing maintenance downtime. The metric dimensions (5.3mm ID, 10mm OD) provide exact compatibility, enhancing assembly efficiency and preventing fluid ingress in pumps, mixers, and conveyor systems.

Specification Summary & Compliance

This flat washer meets precise dimensional tolerances for M5 screw applications with 5.3mm inner diameter and 10mm outer diameter. Manufacturing adheres to FDA standard 21 CFR 177.2600 for food contact, alongside full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. The EPDM rubber composition ensures consistent performance within specified thickness parameters (1.190mm–1.950mm), validated for food-grade and industrial hygiene requirements.
