HNBR O-Rings (HSN) Hydrogenated Nitrile Green/Black
Hydrogenated Nitrile O-Rings manufacturing process results in the superior heat, ozone, chemical resistance and mechanical characteristics of HNBR over standard Nitrile. Standard HNBRs typically have 36% ACN content which iimproves fuels and polar lubricants resistance. 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.
