This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
HNBR (Hydrogenated Nitrile) offers excellent abrasion and tear strength, improved ozone and weathering resistance over standard nitrile. This material stands up to heat and oxidation, ozone and weathering, and sour gas and amine inhibitors. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Applications involving esters or ketones call for a different compound.
Typical settings include engine timing systems, commercial refrigeration, and automotive air conditioning.
HS70203 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
