The ASC ENGINEERED SOLUTIONS 830527743 is a black steel extra-heavy (XH) pipe nipple sized at 1-1/4 inches by 4-1/2 inches. This close-tolerance threaded nipple serves as a short pipe extension or connection point in high-pressure or heavy-duty piping assemblies. Fabricated from black steel, it delivers the wall thickness required where standard-weight fittings are not sufficient. Plumbers, pipefitters, and mechanical contractors install this type of nipple in gas distribution, steam, and industrial process piping systems where robust threaded connections are specified.
This XH nipple is suited for residential and commercial mechanical systems that require heavier pipe wall construction. Typical applications include gas supply lines, steam distribution headers, and industrial piping assemblies where standard-weight fittings would not meet pressure or durability requirements. The 1-1/4-inch diameter makes it a common size in medium-capacity gas and steam branch connections throughout commercial mechanical rooms and industrial facilities.
Designed as a standard threaded XH nipple for use in 1-1/4-inch black steel piping systems. Fits standard NPT threaded fittings, couplings, and valves rated for black steel pipe assemblies.
Installation is performed by licensed plumbers or pipefitters following applicable code requirements such as the IFGC or ASME B31 piping standards. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape rated for the service medium before making up threaded joints. Inspect threads on mating fittings for damage before assembly to ensure a leak-free connection.
