• Chemical & Moisture Resistance – Neoprene rubber construction resists oils, greases, and cleaning agents common in food industry environments.
• Precision Sizing – 0.49" ID and 1.062" OD ensure perfect fit for 1/2" screws, preventing misalignment and leakage.
• Regulatory Conformity – Meets RoHS 3 and REACH standards, supporting global supply chain requirements and environmental safety.
• Durable White Finish – Color-coded for food-grade applications and maintains visibility for inspection and cleanliness protocols.

Professional Applications & Engineering Value

Engineered for demanding food industry applications, these neoprene rubber flat washers address critical sealing challenges in processing machinery, packaging systems, and sanitary equipment. The FDA-compliant neoprene material prevents chemical leaching and withstands repeated exposure to steam, detergents, and temperature fluctuations from freezer units to hot fill lines. With a Durometer 55A hardness, the washer creates reliable, long-lasting seals that absorb operational vibrations and compensate for surface irregularities on 1/2" screw connections. This combination of temperature resistance and compliance with RoHS 3 and REACH standards makes it an essential component for maintaining hygiene and operational uptime in food production facilities.
