NBR Parker N0507-90 O-Ring, Size 003, 0.056" ID x 0.060" CS

Parker’s N0507-90 is a 90-durometer black nitrile (NBR, Buna) O-ring material. N0507-90 has excellent low temperature properties (-65°F) and meets AMS-P-5510, a specification for aircraft hydraulic systems. N0507-90 is used successfully within Compressed Natural Gas (CNG) applications. (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.
