The ASC Engineered Solutions 830038402 is a black steel pipe nipple sized at 2 inches by 5-1/2 inches, used to connect threaded pipe sections in gas, oil, and industrial piping systems. Black steel nipples are a standard fitting for low-pressure gas distribution and hydronic heating lines where corrosion resistance from galvanizing is not required. This nipple is imported and manufactured from black steel, providing solid mechanical strength for standard threaded pipe assemblies. Plumbers, pipefitters, and HVAC technicians install this type of fitting as part of routine piping rough-in and system assembly work.
This nipple is suited for residential and light commercial applications including natural gas supply lines, propane distribution, steam lines, and hydronic heating systems. The 2-inch diameter accommodates higher-flow runs where smaller fittings would create unacceptable pressure drop. At 5-1/2 inches in length, it provides a short extension between two threaded pipe connections, making it useful for close-quarter piping layouts where a longer nipple or field-cut pipe is impractical.
Designed as an OEM-style replacement and standard-use fitting for 2-inch threaded black steel piping systems in residential and commercial gas, hydronic, and industrial applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including the IFGC and IPC. Shut off and depressurize the gas or fluid supply before removing or installing any threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-tighten threaded connections, as this can damage the fitting or adjacent pipe threads.
