Metric HNBR O Ring Size Encapsulated Waterproof Rubber Seals For Oil And Gas

What are HNBR O-rings?

HNBR (hydrogenated acrylonitrile butadiene rubber) is one of the elastomers with the widest range of

applications in industry.

Not only sealing rings, but also timing belts and hydraulic hoses are made from this material.

This already shows the potential of HNBR for use as an O-ring: The combination of good mechanical strength

and a high maximum operating temperature characterizes HNBR sealing elements.

It is also resistant to mineral oil-based media. HNBR is produced by partially or fully hydrogenating the O-ring

material NBR (acrylonitrile butadiene rubber). 

This step enables key improvements in the properties of HNBR compared to NBR, above all resistance to

weathering and ozone as well as higher temperature resistance.

Many heavily loaded NBR O-rings are increasingly being replaced by variants made of the higher-performance

but also more cost-intensive HNBR.
