The ASC Engineered Solutions 830044608 is a black steel pipe nipple sized at 2.5 inches by 11 inches, designed for use in threaded pipe assemblies across plumbing, HVAC, and gas distribution systems. Black steel nipples serve as short threaded connectors between fittings, valves, and equipment, carrying gas, air, or other media through a piping network. At 4.80 pounds, this nipple is a substantial fitting suited for 2.5-inch pipe runs where a reliable threaded connection is required. Licensed plumbers, pipefitters, and HVAC technicians regularly specify black steel nipples for natural gas, propane, and low-pressure steam applications.
This nipple is appropriate for residential and commercial installations where 2.5-inch black steel threaded pipe is specified. Common applications include gas supply lines to boilers, furnaces, unit heaters, and rooftop HVAC equipment, as well as compressed air distribution and low-pressure steam systems. Its 11-inch body length suits close-proximity connections where a standard close or short nipple would be insufficient but a full-length pipe section is not needed.
Designed as a standard NPT-threaded black steel pipe nipple for use with 2.5-inch threaded fittings, valves, and equipment connections in gas, air, and low-pressure steam piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the IFGC for gas piping or the IPC for plumbing systems. Shut off and depressurize the supply line before threading or unthreading any fitting. Apply appropriate thread sealant or PTFE tape rated for the intended service medium to all NPT threads before assembly. Do not over-tighten threaded connections; hand-snug and then wrench-tighten to avoid cracking fittings or distorting threads.
