-049 BLACK CHLOROPRENE 70D O-RING

Part number N70049 is an AS568-049 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 4.989 in (126.72 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 5.129 in (130.28 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to moderate petroleum oil exposure, refrigerants and ammonia, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) is known for strong performance in refrigeration circuits 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). Exposure to ketones or strong oxidizing acids will shorten service life.

Typical settings include weather sealing and enclosures, HVAC and refrigeration, and marine equipment.

N70049 ships individually. Unit weight is approximately 1.4 g and nominal inside diameter is listed as 5 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
