The ASC Engineered Solutions 830527685 is a black steel extra heavy (XH) pipe nipple sized at 1-1/4 inches by 3 inches. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other pipe components in a piping assembly. This nipple is manufactured from black steel, making it suitable for gas, oil, and steam distribution systems where a non-galvanized fitting is required. Plumbers, pipefitters, and mechanical contractors install this type of nipple in both new construction and retrofit applications. The extra heavy wall rating provides greater pressure capacity than standard weight nipples, suited for higher-demand installations.
This black steel XH nipple is used in commercial and industrial piping systems, as well as residential gas distribution applications. It fits into assemblies requiring a 1-1/4-inch nominal pipe thread connection with a 3-inch overall length. Common install scenarios include gas line branches, boiler room piping, and mechanical room distribution headers where black iron fittings are specified or required by code.
Designed as a standard replacement or new-installation nipple for 1-1/4-inch NPT piping systems using black iron or black steel fittings and valves.
Installation is performed by licensed plumbers or pipefitters following applicable local mechanical and fuel gas codes, including IFGC requirements for gas piping systems. Shut off and depressurize the piping system fully before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape rated for the service medium before assembly. Do not over-tighten threaded connections, as this can damage the fitting threads.
