Key Features & Benefits at a Glance

• FDA-compliant material ensures safe, non-contaminating use in food processing and handling equipment.
• Excellent chemical and temperature resistance from -30°F to 220°F provides reliable performance in demanding environments.
• Durometer 55A hardness offers optimal sealing and vibration damping to protect machinery and reduce noise.
• Precise M8 metric sizing (8.4mm ID, 16mm OD) ensures easy installation and consistent fit with standard fasteners.
• RoHS 3 and REACH compliance guarantees adherence to strict environmental and safety regulations.
• Durable neoprene rubber construction resists degradation from oils, moisture, and repeated sterilization cycles.
• Flat washer design distributes load evenly, preventing surface damage and extending equipment life.

Professional Applications & Engineering Value

Engineered for the rigorous demands of the food industry, these M8 neoprene rubber flat washers address critical challenges like chemical exposure, thermal cycling, and hygiene compliance. The neoprene material provides inherent resistance to oils and cleaning agents, while the FDA-compliant formulation prevents contamination in direct food contact zones. With a temperature range of -30°F to 220°F, they maintain elasticity and sealing integrity in both freezing storage and hot washdown environments. The flat washer design and Durometer 55A hardness ensure effective vibration damping and load distribution, reducing wear on metric M8 screw connections in mixers, conveyors, and packaging machinery. This combination of material properties and precise dimensions delivers long-term reliability, minimizing downtime and maintenance costs in food processing operations.

Specification Summary & Compliance

This flat washer adheres to metric sizing standards with an inner diameter of 8.4 mm, outer diameter of 16 mm, and thickness ranging from 1.168 mm to 1.981 mm, designed for M8 screw size applications. It meets FDA compliance under 21 CFR 177.2600 for food contact, along with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives. The neoprene rubber material with Durometer 55A hardness ensures consistent performance, supporting use in food-grade and industrial settings where regulatory conformity is essential.
