NE40BK00 is Canyon’s standard 40 Shore A black Neoprene (CR) compound engineered for flexible, general-purpose O-rings and gaskets requiring low hardness and good environmental resistance. This material offers reliable performance against weathering, moderate heat, and low-temperature solvents and refrigerants, making it suitable for HVAC, industrial, and light-duty sealing applications. With a service temperature range of -40°C to 121°C (-40°F to 250°F), NE40BK00 maintains elasticity and sealing contact through temperature cycling while accommodating surface irregularities. Its low durometer supports easy installation and reduced risk of damage in static and light dynamic seals. Compare NE40BK00 to Parker C0267-50 for similar low-durometer Neoprene sealing performance.
