NE70BK60 is Canyon’s MIL-R-3065 Grade 70 compliant, 70 Shore A black Neoprene (CR) compound engineered for O-rings and gaskets that require dependable low-temperature flexibility and stable compression set performance. This material provides good resistance to weathering, moderate heat, and low-temperature solvents and refrigerants, supporting reliable sealing in aerospace, military, HVAC, and general industrial applications. With a service temperature range of -40°C to 125°C (-40°F to 257°F), NE70BK60 maintains elasticity and sealing force through temperature cycling in static and light dynamic service. Its balanced durometer delivers consistent sealing without excessive stiffness, helping reduce installation damage and long-term set. Compare NE70BK60 to Parker C1124-70 for similar MIL-qualified Neoprene sealing performance.
NE70BK60 meets ASTM D2000 M3BC710 requirements and MIL-R-3065 Grade 70, making it suitable for programs that require specification alignment, repeatability, and traceability. This compound is commonly selected where cost-effective Neoprene performance is needed alongside documented military standards. Canyon Components offers NE70BK60 as a practical solution for low-temperature Neoprene O-rings and gaskets across regulated and industrial environments.
