The ASC Engineered Solutions 830514105 is a black steel extra heavy (XH) pipe nipple sized at 1/2 inch by 3-1/2 inch. This close-tolerance threaded fitting connects sections of pipe in pressurized systems where additional wall thickness is required beyond standard schedule fittings. It is used in gas, steam, air, and industrial fluid piping assemblies. Licensed plumbers, pipefitters, and HVAC technicians install this type of nipple as part of rough-in work, equipment connections, and system modifications. The black steel construction makes it appropriate for non-potable applications including gas distribution and industrial process lines.
This nipple is suited for commercial and industrial piping installations where extra heavy wall thickness adds margin for higher-pressure service or where threaded joint durability is a priority. It fits standard 1/2 inch NPT threaded systems and serves as a connecting piece between valves, tees, elbows, couplings, and other threaded fittings. Import-sourced product intended for professional trade use.
Designed as a standard threaded replacement or new-installation nipple for 1/2 inch NPT piping systems in commercial and industrial applications.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC requirements for the service type. Shut off and depressurize the affected piping system before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly. Do not over-torque threaded connections, as this can damage fittings or cause joint failure.
