Parker’s N0674 is a 70-durometer general purpose Nitrile (NBR, Buna) O-ring material. N0674-70 is UL listed. The sizes offered below represent the standard AS-568 offering. For an additional testing charge, parts can be certified to Mil-G-21569. (NBR) O-rings offer the best combination of properties across a variety of O-ring applications. 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.
