Its HNBR material provides abrasion resistance, heat aging resistance and performance in many oil, refrigerant and fluid power applications. It is with a listed temperature range of -40°F (-40°C) to 325°F (163°C), which can help narrow material selection for heat, cold or process exposure. The black color and round profile provide a practical visual identifier during receiving, stocking and installation.

The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. Common purchasing identifiers for this product include the material name, O-ring type, dimensional size, hardness and intended sealing application. Those attributes make the item easier to compare for maintenance, OEM production, MRO replacement and reseller catalog use.
