This o-ring is supplied in AS568-019 black Neoprene (Chloroprene) 70 Shore A measuring an inside diameter of 0.801 in (20.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.941 in (23.9 mm), catalogued under part number N70019. It creates a positive seal at flange, piston and rod interfaces without added hardware.
It resists mild acids, refrigerants and ammonia, and sunlight and salt spray. That behavior comes from the compound itself: Neoprene (Chloroprene) is widely chosen for dependable general-purpose sealing in exposed installations, a balanced combination of oil and weather resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to chlorinated solvents or strong oxidizing acids will shorten service life.
It sees regular use in transit and rail, general industrial, and marine equipment.
Order part number N70019, sold individually. Unit weight is approximately 0.251 g. Check the compound against your process media, pressure and temperature before committing to a design.
