Highly Saturated Nitrile (HNBR)
HNBR is known for its physical strength and retention of its properties after long-term exposure to heat, oil, and chemicals.
Standard Durometer & Colors
HNBR O-Rings typically have a standard durometer range of 50 to 90 Shore A, with 70 and 80 being the most common.
The common colors for Highly Saturated Nitrile O-Rings are black, green, yellow, and brown.
Temperature Range for HNBR
Highly Saturated Nitrile is good over a broad range of temperatures from minus 399 degrees and up to 302 degrees.
Recommended Use of HNBR O-Rings
HNBR has excellent resistance to most common automotive fluids like engine oil, coolant, and fuel, as well as many industrial chemicals. HNBR is widely used in performance-demanding applications because of its unique properties and higher temperature rating.

HNBR Benefits
Highly Saturated Nitrile fills the gap between Nitrile (NBR) and Viton (FKM) because of its excellent resistance to motor oil, ATF, oxidized fuels and lubricating oils when high-temperature conditions require high tensile strength.
The automotive market is the largest consumer of HNBR. They use it for many dynamic and static seals, hoses, and belts.
