The ASC Engineered Solutions 830514204 is a black steel extra heavy (XH) pipe nipple used to connect threaded pipe sections in gas, air, and general-purpose piping systems. Sized at 1/2 inch by 6 inches, it is manufactured from black steel for strength in higher-pressure and higher-temperature applications where standard-weight fittings are insufficient. The extra heavy wall thickness makes it a reliable choice when additional durability or pressure capacity is required. Licensed plumbers, pipefitters, and mechanical contractors install this type of nipple in both new construction and retrofit work.
This nipple is suited for residential and commercial piping installations where threaded black steel fittings are specified. Common applications include natural gas supply lines, compressed air distribution, and steam or hot-water heating systems. The 1/2 inch diameter and 6 inch length make it a frequently used size in branch connections, equipment tie-ins, and close-quarter runs where a longer rigid nipple is preferred over a union or flexible connector.
Designed as an OEM-style replacement or new-installation fitting for 1/2 inch NPT threaded black steel piping systems in gas, air, and mechanical piping applications.
Installation of black steel pipe nipples on gas lines must be performed by a licensed plumber or pipefitter in accordance with IFGC and local mechanical codes. Shut off and bleed down the supply line before disassembling any existing fittings. Apply a listed thread sealant or pipe dope rated for the service medium to all male threads before assembly. After installation, leak-test all gas connections with an approved detection solution before restoring service.
