Product Specification

-
The N70355 is an AS568-355 black Neoprene (Chloroprene) 70 Shore A O-Ring supplied with an inside diameter of 5.225 in (132.72 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.645 in (143.38 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Neoprene (Chloroprene) is known for inherent flame-retarding characteristics and good resilience across a moderate temperature band. Expect good resistance to moderate petroleum oil exposure, mild acids, and sunlight and salt spray. 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 aromatic hydrocarbons are present.

Maintenance and OEM teams specify it across transit and rail, HVAC and refrigeration, and general industrial.

Stocked as N70355 and sold individually. Unit weight is approximately 13.68 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
