HNBR O Ring

Hydrogenated Nitrile Rubber O-Rings (HNBR)
Highly Saturated Nitrile Green O-rings in 70 durometer. Hydrogenation of nitrile rubber removes most of the residual unsaturation in the polymer to make it far less vulnerable to attack by heat, ozone, and oxygen. In fact, due to superior oil and temperature resistance, Highly Saturated Nitrile can sometimes be substituted for more costly fluorocarbon rubber. It is frequently used in automotive air conditioning systems employing R-134a refrigerants. It exhibits good resistance to petroleum based oils, compression set and a variety of Freons.

The Hydrogenated Nitrile Butadiene Rubber (HNBR) O-ring has quickly grown in importance over the last years, due to its excellent cost-performance balance and use in highly demanding applications such as automotive, industrial applications which require high performance.

HNBR O-ring meets higher temperatures than standard NBR
The HNBR O-ring has recently been developed to meet higher temperatures than standard NBR while retaining resistance to petroleum based oils. 

HNBR O-ring has excellent resistance to oils and chemicals
Obtained by hydrogenating the nitrile copolymer, the HNBR O-ring fills the gap left between NBR, EPDM and FKM elastomers where high temperature conditions require high tensile strength while maintaining excellent resistance to oils and chemicals.
