• Broad temperature resistance from -20°F to 175°F, maintaining flexibility and seal integrity in varying operational environments.
• Superior chemical resistance against oils, greases, and many industrial fluids, extending service life in demanding conditions.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, supporting global supply chain requirements and sustainable practices.
• Precise dimensional fit with 0.164" ID and 0.313" OD, ensuring easy installation and consistent performance on standard No. 8 fasteners.
• Durable and non-marking white rubber construction, ideal for clean environments like food processing where contamination must be avoided.

Professional Applications & Engineering Value

These Buna-N rubber flat washers are engineered to address critical sealing challenges in the food industry, where equipment must withstand frequent washdowns, temperature fluctuations, and exposure to chemicals. The FDA compliant material ensures safety in food contact applications, preventing contamination and meeting strict hygiene standards. With a temperature range from -20°F to 175°F, they maintain elasticity and sealing capability in both freezing and moderate heat conditions, reducing the risk of leaks in machinery such as mixers, conveyors, and packaging systems. The 60A durometer hardness offers optimal compression for No. 8 screws, providing a tight seal that resists vibration and extends the life of connected components. This makes them a reliable flat washer solution for engineers seeking durable, food-grade sealing performance in compliance with industry regulations.
