-356 BLACK CHLOROPRENE 70D O-RING

APG stocks the N70356, an AS568-356 black Neoprene (Chloroprene) 70 Shore A O-Ring supplied with an inside diameter of 5.35 in (135.89 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.77 in (146.56 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists refrigerants and ammonia, mild acids, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) is valued for good resilience across a moderate temperature band and inherent flame-retarding characteristics. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving chlorinated solvents or ketones call for a different compound.

You will find this material specified across weather sealing and enclosures, HVAC and refrigeration, and general industrial.

This item is sold individually under part number N70356. Unit weight is approximately 13.8732 g and nominal inside diameter is listed as 5 3/8 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.
