Nitrile O-Rings Description:

Nitrile O-Rings butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers (1,2-butadiene and 1,3-butadiene). Although its physical and chemical properties vary depending on the polymer’s composition of nitrile, this form of synthetic rubber is generally resistant to oil, fuel, and other chemicals (the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material).

Nitrile is one of the most widely used elastomer in the sealing industry and is extensively used in O-ring and sealing applications. The popularity of nitrile is attributed to its excellent resistance to petroleum products and its ability to be compounded for application over a temperature range of -22°F to 212°F. Nitrile offers excellent compression set, tear, and abrasion resistance.

Properties:

Good Wear Resistance, Good Compression Set Resistance, Good Short-Term Resilience, Good Permeation Resistance. *Can be ordered in higher durometers for high pressure applications to prevent extrusion or ordered in lower durometers for fast sealing in lower pressure applications.

Temperature Range:

-35º F to 250EF

Recomended For:

Silicone Greases / Oils, Water, Petroleum Oils / Fuels, Ethylene Glycol Fluids

NOT Recomended For:

Ketones (MEK), Halogenated Hydrocarbons, Auto / Aircraft Brake Fluids, Strong Acids, Sunlight, Ozone, Weathering.
