The ASC ENGINEERED SOLUTIONS 830540803 is a black steel extra-heavy (XH) pipe nipple sized at 2.5 inches by 6 inches. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other piping components in a run. This nipple is manufactured from black steel, making it suited for gas distribution, steam, and industrial fluid piping systems where uncoated steel is the standard material. Licensed plumbers, pipefitters, and HVAC technicians install nipples of this type when assembling or extending threaded pipe networks. The extra-heavy wall thickness provides increased pressure capacity compared to standard or schedule 40 fittings.
This nipple is used in residential and commercial piping installations where black steel threaded fittings are required. Typical applications include natural gas supply lines, propane distribution, steam systems, and industrial fluid transfer. The 2.5-inch nominal pipe size suits larger-diameter runs commonly found in commercial mechanical rooms, boiler connections, and main gas distribution headers. It is not intended for potable water service. The import designation indicates this fitting is manufactured outside the United States.
Designed as a standard threaded replacement nipple for black steel piping systems using 2.5-inch nominal pipe size components. Compatible with NPT-threaded fittings, valves, and couplings of the same nominal diameter.
Installation should be performed by a licensed plumber or pipefitter following applicable local mechanical and plumbing codes, including IPC and IFGC requirements where gas service is involved. Shut off and depressurize the piping system fully before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Use a pipe wrench of appropriate size to achieve proper thread engagement without over-stressing the fitting.
