The ASC Engineered Solutions 830034807 is a black steel pipe nipple sized at 1-1/2 inches by 7 inches, designed for use in threaded pipe assemblies across a range of plumbing, HVAC, gas distribution, and industrial piping systems. Constructed from black steel, this nipple provides the durability required in high-pressure and high-temperature service applications. At 1.45 pounds, it offers solid construction for demanding installations. Licensed plumbers, pipefitters, and HVAC technicians typically specify black steel nipples for gas lines, hydronic heating loops, and similar black-iron piping configurations.
This nipple is suited for residential and light commercial installations where threaded black steel piping is required. Common applications include natural gas supply lines, propane distribution, steam systems, and hydronic heating systems. The 7-inch length makes it useful for close-quarter connections and riser extensions where standard close or short nipples are insufficient. It threads directly into standard NPT fittings, valves, and couplings in matching 1-1/2-inch pipe size systems.
Designed as an OEM-style threaded fitting for use in standard 1-1/2-inch NPT black steel piping systems, including gas distribution, steam, and hydronic heating assemblies.
Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, including IFGC requirements for gas piping systems. Shut off and depressurize the supply line before beginning any work on the piping system. Apply appropriate pipe thread sealant or PTFE tape rated for the intended service medium before threading the nipple into fittings. Do not over-tighten threaded connections, as this can damage threads and compromise joint integrity.
