In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Neoprene (Chloroprene) is specified for a balanced combination of oil and weather resistance, dependable general-purpose sealing in exposed installations. This material stands up to moderate petroleum oil exposure, ozone and weathering, and refrigerants and ammonia. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or strong oxidizing acids will shorten service life.
Typical settings include HVAC and refrigeration, transit and rail, and weather sealing and enclosures.
Stocked as N70147 and sold individually. Unit weight is approximately 1.67 g and nominal inside diameter is listed as 2 11/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
