-378 BLACK CHLOROPRENE 70D O-RING

Ordered as N70378, this is an AS568-378 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 10.475 in (266.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.895 in (276.73 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists ozone and weathering, moderate petroleum oil exposure, and refrigerants and ammonia. That behavior comes from the compound itself: Neoprene (Chloroprene) is known for inherent flame-retarding characteristics and dependable general-purpose sealing in exposed installations. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where chlorinated solvents or ketones are present.

Common environments for this compound include general industrial, marine equipment, and HVAC and refrigeration.

Stocked as N70378 and sold individually. Unit weight is approximately 26.6618 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
