Parker’s N0508-75 is a 75 Shore A black nitrile rubber (NBR) compound developed for food-contact and sanitary sealing applications that require FDA and USDA compliance. Designed to operate within a service temperature range of -30°F to 180°F, it provides reliable sealing performance in contact with petroleum-based oils, water up to 212°F, salt and alkali solutions, and weak acids. The balanced durometer offers good compression set resistance and mechanical stability, supporting consistent sealing in static and light dynamic applications. Its formulation makes it suitable for regulated environments where cleanliness, traceability, and material compliance are essential.
N0508-75 is commonly used for O-rings and gaskets in food processing equipment, packaging machinery, and industrial systems that require FDA-compliant elastomers. It is not recommended for aromatic fuels, strong acids, glycols, ozone exposure, or polar solvents. This compound provides a practical nitrile solution where oil resistance and food-grade compliance intersect. Canyon Components offers equivalent FDA- and USDA-compliant NBR materials designed to match the temperature capability, fluid compatibility, and regulatory profile of Parker N0508-75.
