-219 BLACK CHLOROPRENE 70D O-RING

The N70219 is an AS568-219 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 1.296 in (32.92 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.574 in (39.98 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists moderate petroleum oil exposure, mild acids, and refrigerants and ammonia. That behavior comes from the compound itself: Neoprene (Chloroprene) is widely chosen for strong performance in refrigeration circuits and inherent flame-retarding characteristics. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong oxidizing acids or ketones.

Common environments for this compound include transit and rail, HVAC and refrigeration, and marine equipment.
