-241 BLACK CHLOROPRENE 70D O-RING

Part number N70241 is an AS568-241 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 3.859 in (98.02 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.137 in (105.08 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against refrigerants and ammonia, sunlight and salt spray, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) offers inherent flame-retarding characteristics and good resilience across a moderate temperature band. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or aromatic hydrocarbons.

Common environments for this compound include transit and rail, general industrial, and marine equipment.

Order part number N70241, sold individually. Unit weight is approximately 4.3758 g and nominal inside diameter is listed as 3 7/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
