NBR O-rings | Materials explained simply | Sealing Academy
Alongside FKM or HNBR, NBR (nitrile butadiene rubber) is one of the most frequently used elastomers for sealing elements. The material is characterized by advantageous mechanical properties and a broad resistance profile. The wide range of applications for these O-rings is limited only by their restricted suitability for high temperatures.

Which O-ring material is right for my application?
Aug 18, 2020 · Temperature Range: -40° to +250°F, although that’s an average for the lower and upper tolerances for the various nitrile butadiene rubber (NBR) compounds manufactured by Parker. Parker’s Buna-N compound, which ranges from 70 to 90 durometer hardness nitrile, withstands temperatures from -30°F up to 250°F which includes compounds N0674.
O-Ring and Rubber Seal Materials: NBR, FKM, EPDM
Apr 27, 2020 · NBR is compatible with petroleum fluids (including dinosaur and synthetic lubricating oils, pure gasoline, and diesel fuel). This makes it a good choice for seals in fuel systems running pure gasoline (no ethanol blends) or diesel (not biodiesel). NBR is also fully compatible with water and ethylene glycol coolants.
Nitrile / NBR | O-Ring
NBR is the standard material for hydraulics and pneumatics. NBR resists oil-based hydraulic fluids, fats, animal and vegetable oils, flame retardant liquids (HFA, HFB, HFC), grease, water, and air. Special low-temperature compounds are available for mineral oil-based fluids.
