Product Specification

-
Ordered as N70239, this is an AS568-239 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 3.609 in (91.67 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.887 in (98.73 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Neoprene (Chloroprene) is widely chosen for dependable general-purpose sealing in exposed installations, a balanced combination of oil and weather resistance. This material stands up to sunlight and salt spray, moderate petroleum oil exposure, and mild acids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to chlorinated solvents or ketones will shorten service life.

It sees regular use in weather sealing and enclosures, marine equipment, and general industrial.

N70239 ships individually. Unit weight is approximately 4.1021 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
