Professional Applications & Engineering Value

Engineered for the food industry, these Buna-N rubber flat washers address critical sealing and safety challenges. The FDA compliant white material prevents bacterial growth and withstands frequent washdowns with cleaning agents, while the temperature range from -20°F to 175°F ensures performance in both refrigeration and mild heating processes. The flat washer design and Durometer 60A hardness provide a compressible seal that absorbs vibration in machinery, reducing noise and preventing fastener loosening. Ideal for No. 6 screw sizes, they are commonly used in food processing equipment, conveyor systems, and packaging machinery where chemical resistance and regulatory compliance are paramount. This combination of material properties and inch system precision enhances equipment reliability and minimizes downtime.
