The ASC Engineered Solutions 830039400 is a black steel pipe nipple sized at 2 inches by 8 inches, used to create threaded pipe connections in gas, air, and fluid distribution systems. Black steel nipples are a standard fitting in commercial and residential piping runs where galvanized coatings are not required. At 2.28 pounds, this nipple is a close-cut threaded connector that bridges two female-threaded fittings or valves in a straight run. It is installed by licensed plumbers, pipefitters, and HVAC technicians working on gas lines, compressed air headers, and hydronic heating systems.
This fitting is suited for residential and light commercial applications where a 2-inch nominal threaded connection is required. Common installation scenarios include gas supply mains, boiler piping, compressed air distribution, and black iron plumbing rough-in work. The 8-inch length provides additional reach between fittings compared to shorter nipple sizes, making it useful where standard close or short nipples do not span the required distance.
Designed as a standard-pattern replacement or new-installation black steel threaded pipe nipple for 2-inch NPT piping systems in gas distribution, compressed air, and hydronic heating applications.
Black steel pipe nipples are installed by licensed plumbers, pipefitters, and HVAC technicians. Shut off and depressurize the piping system before removing or installing any threaded fitting. Apply an appropriate thread sealant or listed pipe thread compound rated for the specific service medium before assembly. Gas piping installations must comply with the International Fuel Gas Code and all applicable local codes.
