OSK™ O-Ring Service Kits HNBR 70 Industrial O-Ring Kit

This kit contains a total of 436 70 Durometer O-Rings in 36 different sizes, providing an extremely low cost per size value.

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. HNBR can be can be either peroxide or sulfur cured, depending on the degree of unsaturation achieved by the hydrogenation process, but peroxide is almost always used due to the good heat stability properties of the peroxide cross links. It can be compounded for both low and high temperature use.

Highly Saturated Nitrile Butadiene Rubber

HNBR, or HSN, is a hydrogenated NBR for increased saturation of the butadiene segment of the main carbon polymer chain. This gives HNBR better thermal stability, greater tensile strength, greater wear and extrusion resistance, increased resistance to ozone and oxygen, and broader chemical resistance compared to a standard NBR. HNBR It is often seen in automotive air conditioning applications due to its excellent resistance to R-134a refrigerants. With minimal degredation, HNBR may be used from -40°F to 300°F  for extended periods.

HNBR / HSN Recommended uses:

  • Petroleum oils and fluids.
  • Automotive refrigerants (R134-a)
  • Hydrogen sulfide (H2S) or sour gas

  • Silicone greases and oils
  • Di-ester base lubricants (MIL-L-7808).
  • Ethylene glycol base fluids (Hydrolubes)
