NB70BK00 is Canyon’s standard 70 Shore A black nitrile rubber (NBR) compound designed for general-purpose O-rings and gaskets used in oil-handling and industrial sealing applications. This cost-effective material provides good abrasion resistance and low compression set, supporting reliable long-term sealing performance in static and light dynamic service. With a service temperature range of -35°C to 122°C (-31°F to 252°F), NB70BK00 performs well in contact with petroleum-based oils and common industrial fluids. It is widely used in pumps, valves, hydraulic components, and general machinery where dependable nitrile performance and value are key considerations. Compare NB70BK00 to Parker N0674-70, N1470-70, and NA151-70 for similar 70 Shore A NBR sealing applications.
