White FDA Buna-N O-Rings | NBR 70 Duro | Food & Dairy Grade

White FDA Buna-N O-Rings are food grade nitrile (NBR) seals in a 70 durometer white compound, used to seal food, beverage, dairy, and drinking water equipment where FDA compliance is required. Nitrile stands up well to oils, fuels, greases, and water, which makes it a common choice for pumps, valves, and processing gear. The white color makes the seal easy to spot on light-colored machinery and helps catch contamination fast. 70 durometer is a medium hardness that fits most standard grooves and gives reliable general sealing.
