Hydrogenated Nitrile o-rings come from adding hydrogen to the nitrile molecular chain to make it more stable. The addition of hydrogen reduces the number of carbon-carbon double bonds, making it less reactive. It can be used in petroleum oils and fuels, R134a refrigerant gas, silicone oils and greases, ozone applications, vegetable and animal fats and fluids, water and steam (up to 300° F).
Engineered Seal Products has the expertise and inventory for your hydrogenated nitrile (HNBR) o-ring applications. For over 50 years, ESP has been the leading engineering, quality, and supply chain choice for both standard and custom sealing applications. A seal, no matter the application, has to do just that.

What's The Difference Between Hydrogenated Nitrile (HNBR) & Nitrile (NBR) O-Rings?
In comparison with NBR, HNBR has better abrasion resistance, tear resistance, high-temperature properties and resistance to chemical attacks.
