This o-ring is supplied in AS568-335 black Neoprene (Chloroprene) 70 Shore A measuring an inside diameter of 2.725 in (69.22 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.145 in (79.88 mm), catalogued under part number N70335. It compresses into its gland to block fluid or gas migration across a joint.
It resists sunlight and salt spray, refrigerants and ammonia, and ozone and weathering. Neoprene (Chloroprene) is widely chosen for inherent flame-retarding characteristics and good resilience across a moderate temperature band. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving strong oxidizing acids or ketones call for a different compound.
It sees regular use in weather sealing and enclosures, HVAC and refrigeration, and marine equipment.
Order part number N70335, sold individually. Unit weight is approximately 7.3236 g and nominal inside diameter is listed as 2 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
