HNBR (Hydrogenated Nitrile) is known for excellent abrasion and tear strength, long service life in refrigerant and oilfield duty. The compound resists modern refrigerants, ozone and weathering, and heat and oxidation. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where strong oxidizing acids or ketones are present.

Maintenance and OEM teams specify it across oilfield and downhole equipment, engine timing systems, and heavy-duty powertrain.

This item is sold individually under part number HS70133. Nominal inside diameter is listed as 1 13/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
