Parker’s NM756-75 is a 75-durometer black nitrile (NBR, Buna) O-ring material. NM756-75 has strong low temperature performance (-65°F) and meets AMS-P-83461, a specification certifying better dynamic service life at 257°F than specification MIL-P-25732. NM756-75 is an excellent general-purpose material that has good mechanical properties when compared to other elastomers. Nitrile compounds perform well in gasoline, crude oil, power-steering fluid, hexane, toluene, water, water-based hydraulic fluids, and dilute bases, such as sodium hydroxide. Because nitriles contain unsaturated carbon-carbon bonds in the base polymer, they are not suitable for exposure to ozone, sunlight, and weathering. Download our guide here.
