The N70456 is an AS568-456 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 13.475 in (342.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 14.025 in (356.24 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The material holds up against refrigerants and ammonia, moderate petroleum oil exposure, and mild acids. Neoprene (Chloroprene) is specified for a balanced combination of oil and weather resistance, good resilience across a moderate temperature band. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to strong oxidizing acids or ketones will shorten service life.
Maintenance and OEM teams specify it across general industrial, marine equipment, and weather sealing and enclosures.
