The ASC Engineered Solutions 830030409 is a black steel close-pattern pipe nipple sized at 1-1/4 inches by 7 inches. It serves as a short threaded pipe segment used to connect fittings, valves, and other threaded components in piping assemblies. Black steel construction makes it a standard choice for gas distribution, steam, and industrial fluid systems where corrosion resistance from coatings or galvanizing is not required. Licensed plumbers and pipefitters typically install this fitting in commercial and residential gas lines or steam distribution applications. The part weighs 1.21 pounds and is import-sourced.
This nipple is suited for residential and light commercial piping work where a short threaded extension between two fittings is needed. Common applications include natural gas supply lines, propane distribution, steam heating systems, and general industrial black iron piping assemblies. The 1-1/4 inch diameter accommodates moderate-flow distribution lines. It is installed wherever NPT-threaded black iron connections are specified by code or design.
Designed as a standard NPT-threaded black iron pipe nipple compatible with 1-1/4 inch black iron or malleable iron threaded fittings, couplings, valves, and tees used in gas and steam piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC, or IPC requirements. Shut off and purge gas or steam supply completely before working on any threaded connections. Apply an appropriate thread sealant or listed pipe joint compound rated for the service medium before threading the nipple into fittings. Do not over-tighten threaded joints, as black steel threads can be damaged by excessive force.
