N0674-70 Datasheet

Parker’s N0674-70 is a 70 Shore A black nitrile rubber (NBR) compound designed as a general-purpose sealing material for industrial and fluid-handling applications. Qualified to ASTM D2000 2BG720 and MIL-G-21569 Class I, and UL listed, it provides dependable sealing performance across a service temperature range of -30°F to 250°F. The compound offers good resistance to petroleum-based oils, water up to 212°F, salt and alkali solutions, and weak acids, making it suitable for a wide range of standard O-rings and gaskets. Its balanced hardness supports reliable compression set behavior in static and light dynamic sealing environments.

 

N0674-70 is commonly used in pumps, valves, hydraulic equipment, and general machinery where oil resistance and specification compliance are required. It is not recommended for aromatic fuels, strong acids, glycols, ozone exposure, or polar solvents. Canyon Components offers equivalent NBR materials that match the performance, temperature capability, and compliance profile of Parker N0674-70 for general-purpose sealing applications.
