The ASC Engineered Solutions 830532123 is a black steel extra heavy (XH) pipe nipple sized at 1-1/2 inches by 4 inches. This close-cut threaded fitting connects two female-threaded pipe fittings or valves in gas, steam, and water piping systems. The extra heavy wall construction provides greater pressure capacity and mechanical strength compared to standard-weight nipples. Licensed plumbers, pipefitters, and mechanical contractors install this type of nipple in commercial and industrial piping assemblies where additional wall thickness is required by design or code.
This nipple is suited for residential and commercial applications in black iron gas piping, steam distribution, and general industrial pipe systems. The 1-1/2-inch diameter and 4-inch length make it a common fitting for branch connections, riser assemblies, and equipment drops in mechanical rooms and boiler piping. It is supplied as an import fitting for cost-sensitive projects where domestic certification is not required.
Designed as an OEM-style replacement or new-installation fitting for 1-1/2-inch NPT black iron piping systems in gas and steam mechanical applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as applicable. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium before making up the joint. Do not over-torque threaded connections, as this can damage threads or distort the fitting.
