Nitrile, also known as Buna-N, is the standard to which all the other elastomers are compared. More than half of all sealing needs can be met with nitrile. Because they are versatile and inexpensive, nitriles are the most popular industrial seal material.
Parco’s Nitrile O-rings provide excellent service with gasoline, crude oil, power steering fluid, hexane, toluene, water, water-based hydraulic fluids, and dilute bases such as sodium hydroxide. Individual nitrile compounds have service temperatures that range from -65 to +250°F, including certain compounds formulated for lower temperatures.
