NB70BK16 Datasheet

NB70BK16 is Canyon’s UL 157 approved, 70 Shore A black nitrile rubber (NBR) compound engineered for O-rings and gaskets used in fuel and gas-handling applications. This material is approved for service with gasoline, kerosene, LP gas, naphtha, manufactured and natural gas, and anhydrous ammonia, making it a reliable choice for regulated fuel and gas systems. With a service temperature range of -40°C to 125°C (-40°F to 257°F), NB70BK16 offers good abrasion resistance and low compression set to support consistent sealing performance in static and light dynamic applications. Its balanced durometer provides durability and extrusion resistance while remaining cost effective for high-volume industrial use. Compare NB70BK16 to Parker N0674-70 and N1470-70 for similar UL 157 compliant 70 Shore A nitrile sealing applications.

 

NB70BK16 meets ASTM D2000 2BG715 requirements and is commonly used in valves, fittings, pumps, meters, and general equipment handling fuels and gases. This compound is well suited for applications where UL 157 approval and broad fuel compatibility are required without moving to higher-cost specialty elastomers. Canyon Components offers NB70BK16 as a dependable nitrile solution for fuel and gas sealing needs requiring documented compliance and consistent performance.
