The ASC Engineered Solutions 830056404 is a black steel pipe nipple measuring 4 inches in diameter by 11 inches in length. Pipe nipples are short sections of pipe threaded on both ends, used to connect two female-threaded fittings or to extend a piping run. This nipple is manufactured from black steel, making it well suited for gas distribution, fire suppression, and industrial piping systems. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers of fittings in this size range.
This fitting is sized at 4 inches by 11 inches and is appropriate for use in commercial and industrial piping applications where black steel is the specified material. Common installation scenarios include natural gas mains, propane distribution headers, steam lines, and compressed air systems. It is classified as a non-domestic import product.
Designed as a standard threaded pipe nipple for use in 4-inch black steel piping systems typical of commercial gas distribution, fire suppression, and mechanical piping installations.
Installation of 4-inch black steel pipe nipples should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC, NFPA 54, or local mechanical codes. Shut off and depressurize the piping system completely before making any threaded connections. Apply an approved thread sealant or PTFE tape rated for the intended service medium to all threaded joints before assembly. Do not overtighten threaded connections, and inspect for leaks after restoring system pressure.
