hnbr compounds

Parker's HNBR sealing compounds provide cost-effective solutions in aggressive EOG environments.

N1173-70, N1231-80 and KB163-90 are sealing compounds made from hydrogenated nitrile, a synthetic polymer that results from the hydrogenation of nitrile rubber (NBR). The hydrogenation process gives HNBR materials enhanced thermal stability (up to 149°C/300°F, with short periods at higher temperatures).

HNBR materials also possess superior mechanical properties and enhanced fluid compatibility over standard nitrile compounds. These properties allow HNBR materials to be a  cost-effective bridging compound between nitrile and fluorocarbon elastomers.
