Alongside FKM or HNBR, NBR (nitrile butadiene rubber) is one of the most frequently used elastomers for sealing elements. The material is characterized by advantageous mechanical properties and a broad resistance profile. The wide range of applications for these O-rings is limited only by their restricted suitability for high temperatures.

This popular o-ring material family comparison shows basic rubber material family properties and performance plastic properties. The guide includes generalized recommended o-ring mateiral uses and non-recommended uses with typical material mechanical properties.
O-Ring Handbook (ORD 5700) has been a fixture on the reference shelves of engineers and seal specifiers worldwide. This book contains extensive information about basic sealing elastomer properties, typical O-ring applications, static and dynamic seal design fundamentals, and O-ring failure modes.

NBR is the standard material for hydraulics and pneumatics. NBR resists oil-based hydraulic fluids, fats, animal and vegetable oils, flame retardant liquids (HFA, HFB, HFC), grease, water, and air. Special low-temperature compounds are available for mineral oil-based fluids.
Best known and most widely used are O-rings made of NBR (nitrile rubber). Its excellent oil resistant qualities are combined with superior mechanical properties.
NBR. In contrast to EPDM, the O-ring material NBR has its weaknesses with steam. However, it has very good mechanical properties to offer. Above all, this includes high tear and abrasion resistance. Even if the sealing point is exposed to strong external influences or frequent movements, NBR is elastic enough to seal it reliably.
Nitrile rubber, also known as NBR (acronym for Nitrile Butadiene Rubber), is a synthetic rubber copolymer made from butadiene and acrylonitrile. It is known for its excellent oil and fuel resistance, making it a popular choice for gaskets, seals, hoses, and other applications where exposure to petroleum-based fluids is common.
