HNBR O-Ring Hydrogenated Nitrile Material Selection Guide
HNBR, or hydrogenated NBR, is created by modifying the properties of NBR to increase the materials resistance to ozone, many chemicals, heat, aging, and abrasion. Like NBR, HNBR still holds onto its resistance to oils and fuels.
HNBR o-rings from Marco Rubber are in-stock and ready to ship (custom specifications can typically be accommodated with no additional tooling fees within a few weeks. Leverage the direct pricing power of the world) largest o-ring inventory network and order HNBR o-rings online today!

The information on this page is to the best of our knowledge accurate and reliable. However, Marco Rubber makes no warranty, expressed or implied, that parts manufactured from this material will perform satisfactorily in the customer's application. It's the customer's responsibility to evaluate parts prior to use.
The temperature ranges presented on this page are approximations for dry air service only and should not be used to determine design specifications or end-use temperature limits. Actual temperature range of a compound in an end-use application is highly dependent on part type, hardware configuration, applied forces, chemical media, pressure and thermal cycling effects, and other factors. The most practical way of determining an end-use temperature range is testing in the actual application conditions. Consult a Marco Engineer for more details.
