NE70BK53 is Canyon’s AMS-R-6855 compliant, low-temperature 70 Shore A black Neoprene (CR) compound engineered for O-rings and gaskets that must maintain flexibility and sealing force in extreme cold environments. This material offers excellent low-temperature performance and superior compression set resistance while retaining good resistance to weathering, moderate heat, and low-temperature solvents and refrigerants. With a service temperature range extending down to -61°C (-78°F), NE70BK53 is well suited for aerospace, military, HVAC, and industrial applications exposed to severe cold and thermal cycling. Its balanced durometer supports reliable static and light dynamic sealing without excessive stiffness or installation risk. Compare NE70BK53 to Parker C1124-70 for similar low-temperature, specification-driven Neoprene sealing applications.
NE70BK53 meets ASTM D2000 requirements and is qualified to AMS 3209, MIL-R-6855 Class 2A and 2B Grade 70, and MIL-PRF-6855 Class 2A and 2B Grade 70, making it suitable for programs requiring documented compliance and repeatable performance. This compound is commonly selected where cold-weather capability, durability, and cost control are equally important. Canyon Components offers NE70BK53 as a dependable solution for low-temperature Neoprene O-rings and gaskets in demanding regulated environments.
