-270 BLACK CHLOROPRENE 70D O-RING

Part number N70270 is an AS568-270 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 8.984 in (228.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.262 in (235.25 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against moderate petroleum oil exposure, refrigerants and ammonia, and mild acids. That behavior comes from the compound itself: Neoprene (Chloroprene) is known for strong performance in refrigeration circuits and inherent flame-retarding characteristics. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or aromatic hydrocarbons are present.

Typical settings include general industrial, marine equipment, and weather sealing and enclosures.

N70270 ships individually. Unit weight is approximately 10.355 g. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
