-320 BLACK CHLOROPRENE 70D O-RING

This o-ring is supplied in AS568-320 black Neoprene (Chloroprene) 70 Shore A built to an inside diameter of 1.1 in (27.94 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.52 in (38.61 mm), catalogued under part number N70320. It creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to mild acids, ozone and weathering, and sunlight and salt spray. That behavior comes from the compound itself: Neoprene (Chloroprene) offers good resilience across a moderate temperature band, a balanced combination of oil and weather resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with strong oxidizing acids or ketones.

You will find this material specified across general industrial, marine equipment, and transit and rail.

Stocked as N70320 and sold individually. Unit weight is approximately 3.2684 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
