NB70BK26 is Canyon’s ultra-low temperature, 70 Shore A black nitrile rubber (NBR) compound engineered for O-rings and gaskets used in cold-service industrial sealing applications. This material delivers improved low-temperature flexibility compared to standard nitrile grades while maintaining good abrasion resistance and low compression set for reliable long-term sealing. With a service temperature range down to -55°C (-67°F), NB70BK26 remains elastic during cold starts and temperature cycling in oil-handling and general industrial environments. It is widely selected when dependable nitrile performance is required at temperatures where conventional NBR compounds begin to stiffen. Compare NB70BK26 to Parker N0103-70, N0602-70, N1470-70, and NA151-70 for similar low-temperature 70 Shore A nitrile applications.
NB70BK26 meets ASTM D2000 5BG720 requirements and is commonly used in pumps, valves, hydraulic components, and outdoor equipment exposed to cold climates. Its balanced mechanical properties support consistent sealing in static and light dynamic service without the cost of specialty elastomers. Canyon Components offers NB70BK26 as a cost-effective solution for low-temperature nitrile O-rings and gaskets where flexibility, durability, and value are key design considerations.
