Buna-N Rubber Nitrile Tubing Flex Fittings


Superior strength and high resistance to oils, fuels, and other chemicals

Buna-N Rubber Nitrile Tubing Flex Connector on Feeder
Buna-N Rubber, also called nitrile-butadiene rubber (NBR, Nitrile), is a synthetic rubber that provides excellent resistance to petroleum-based oils as well as mineral and vegetable oil. Our Buna-N Rubber Nitrile Tubing Flex Fittings can withstand a range of conditions in order to suit your specific application. Nitrile / BUNA-N is a copolymer of acrylonitrile and butadiene. It has excellent physical properties, however its claim to fame is based on its resistance to water, petroleum products and fuels. In the white formulation it is 3A rated. Useful temperature range is -40⪚ F to +220° F.

Our Buna-N Rubber Nitrile Flex Connectors display excellent resistance to petroleum-based oils, fuels, water, alcohols, silicone greases, and hydraulic fluids. The chemical and oil resistance, along with a good balance of desirable working properties like low compression set, high abrasion resistance and high tensile strength, makes Nitrile a favorite among chemical and process engineers. Our Buna-N Flex Connectors are also a great choice for applications that require abrasion resistance and metal adhesion. The drawbacks of Buna-N Nitrile include poor ozone and sunlight resistance, below average weather resistance, and poor flame resistance.
