Parker’s N0525-60 is a 60 Shore A black nitrile rubber (NBR) compound designed for general-purpose sealing applications that require balanced flexibility, oil resistance, and documented aerospace compliance. Qualified to SAE J200 (ASTM D2000) M2CH614 and meeting AMS 3212 and AMS 3220, it operates reliably across a service temperature range of -25°F to 250°F while maintaining good compression set resistance and mechanical stability. The compound is compatible with petroleum-based oils, water up to 212°F, salt and alkali solutions, and weak acids, making it suitable for a wide range of industrial and hydraulic environments. Its moderate durometer supports effective sealing in static and light dynamic applications where conformability and durability are both important.
N0525-60 is commonly used for O-rings and gaskets in aerospace-adjacent systems, industrial equipment, pumps, and valves where oil resistance and specification compliance are required. It is not recommended for aromatic fuels, strong acids, glycols, ozone exposure, or polar solvents. This nitrile grade provides a practical, specification-backed solution for everyday sealing needs without the cost of specialty elastomers. Canyon Components offers equivalent NBR materials designed to match the temperature capability, fluid compatibility, and AMS performance profile of Parker N0525-60.
