Buna O-Rings

Buna O-Rings Description:

Nitrile 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).

Buna O-Rings 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.

Buna O-Rings Temperature Range:

-35º F to 250F

Buna O-Rings Recomended For:

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

Buna O-Rings NOT Recomended For:

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