● Petroleum oils and fuels R134a refrigerant gas Silicone oils and greases Ozone applications, improved compression set characteristics Vegetable and animal fats Fluids Water and steam (up to 300° F)Temperature ranges will apply to the majority of media for which the material is potentially recommended.

● With some media however, the service temperature range may be significantly different.always test under acutal service conditions.

● Hydrogenated Nitrile (HNBR) o-rings, also known as Highly Saturated Nitrile (HSN), are made of a synthetic polymer that is obtained by saturating the double bonds in nitrile=s butadiene segments with hydrogen.

● This special hydrogenation process reduces many double bonds in main chains of NBR polymers.This process results in the superior heat, ozone, chemical resistance and mechanical characteristics of HNBR over standard Nitrile.HNBR o-rings are available in 70 durometer, 80 durometer, and 90 durometer.

● HNBR o-rings are preferable for use with petroleum-based oils and fuels, aliphatic hydrocarbons, vegetable oils, silicone oils and greases, ethylene glycol, water and steam (up to 300ºF), and diluted acids, bases, and salt solutions. HNBR o-rings are not preferable for use with chlorinated hydrocarbons, ketones, ethers, esters, and strong acids.
