Nitrile / NBR usage:
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. Most common
material in the scuba industry.
Have been used safely for some time in SCUBA diving by divers using gas
blends referred to as Nitrox. Viton is used because it has a lower
probability of catching fire, even with the increased percentages of
oxygen found in Nitrox. It is also less susceptible to decay under
increased oxygen conditions
