What does NBR 70 mean?
Nitrile 70 rubber (NBR) is the general term for Acrylonitrile Butadiene Copolymer. Nitrile is the most widely used and economical elastomer. Compounds having approximately 50% ACN content are known “High Nitrile” these are usually specified for use with Hydrocarbon fuels.
What does NBR stand for in o-rings?
Also called NBR or Buna-N, nitrile o rings are probably the most economical and widely used elastomer out there. This material has a desirable set of properties including low compression set, high resistance to abrasion and good tensile strength.
Are Danco o-rings nitrile?
Danco o-rings are high abrasive resistant and tempature resistant. Danco o-rings will withstand heat between a temperature range of 86°F to 248°F (-30°C to 120°C). These tough and pliable Buna-Nitrile Rubber (NBR) O-Rings will help provide long-term use for your plumbing needs.
What is a nitrile o-ring?
Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.
What is NBR number?

Is NBR ozone resistant?
Due to its excellent resistance to petroleum products, and its ability to be compounded for service over a temperature range of -35°C to +120°C (-30°F to +250°F), Nitrile /NBR is the most widely used elastomer in the seal industry today. Nitrile compounds do not possess good resistance to ozone, sunlight, or weather.
Is NBR oil resistant?
nitrile rubber (NBR), also called nitrile-butadiene rubber, an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required.
What material are Danco O rings?
Buna-Nitrile Rubber
Danco o-rings are high abrasive resistant and tempature resistant. Danco o-rings will withstand heat between a temperature range of 86°F to 248°F (-30°C to 120°C). These tough and pliable Buna-Nitrile Rubber (NBR) O-Rings will help provide long-term use for your plumbing needs.
Are Danco O rings oil resistant?
General properties include excellent wear resistance, high tensile strength, high hot-tear resistance, low compression set and very good ozone and weathering resistance. They also exhibit good resistance to many oil additives, hydrogen sulphide, high-energy radiation and amines present in crude oil.
How do I know what size O-ring to buy?
Measure the length and the Cross section of the ring. Then divide the length by π (3.142), this will give you the circumference. Take the Cross section from this to give you the Inside diameter.
Is NBR a silicone?
Jehbco manufactures all our products from 100% silicone. Acrylonitrile-butadiene, commonly known as nitrile or NBR, has excellent chemical resistance, similar to silicone. However, the two materials differ in many of other properties.
What is full form of NBR?
Nitrile rubber (NBR), also called nitrile-butadiene rubber, an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene.
