-908 BLACK CHLOROPRENE 70D O-RING

The N70908 is an AS568-908 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 0.644 in (16.36 mm), a cross section of 0.087 in (2.21 mm), and an outside diameter of 0.818 in (20.78 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists moderate petroleum oil exposure, refrigerants and ammonia, and sunlight and salt spray. That behavior comes from the compound itself: Neoprene (Chloroprene) is widely chosen for inherent flame-retarding characteristics and strong performance in refrigeration circuits. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with aromatic hydrocarbons or strong oxidizing acids.

Typical settings include transit and rail, HVAC and refrigeration, and marine equipment.

Stocked as N70908 and sold individually. Unit weight is approximately 0.3247 g and nominal inside diameter is listed as 1/2 inch.
