Canyon’s NB70BU00 is a 70 Shore A blue NBR (Buna-N) compound designed as a dependable, cost-effective solution for general-purpose sealing applications. It offers good abrasion resistance, low compression set, and stable mechanical performance across a service temperature range of -35°C to 122°C (-31°F to 252°F). This material maintains strong tensile strength and high elongation, supporting reliable sealing in both static and light dynamic conditions. NB70BU00 is well suited for industrial equipment, fluid handling systems, and applications where economical nitrile performance is preferred.
NB70BU00 meets ASTM D2000 M2BG714 requirements and delivers consistent performance in oil-resistant sealing environments. It is commonly used where durability, affordability, and availability are key selection factors. Canyon Components offers equivalent and alternative NBR materials to match specific performance needs. Compare to other popular brands of NBR materials such as Parker N0674-70, N1470-70, and NA151-70.
