The ANVIL INTERNATIONAL INC 8700138954 is a black steel pipe nipple sized at 1/2 inch diameter by 8 inches in length. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other threaded pipe components in a run. This nipple features male NPT threads on both ends and is manufactured from black steel, making it suitable for gas distribution, steam, and general-purpose industrial piping systems. Licensed plumbers, pipefitters, and HVAC technicians commonly install these components during new construction and retrofit work.
This nipple is used in residential and light commercial piping applications where a close or extension connection is needed between two threaded components. Common install scenarios include natural gas supply lines, steam heating systems, and black iron distribution headers. The 1/2 inch by 8 inch dimension fills a standard spacing requirement in pipe assemblies where longer close nipples or short spools are needed. It is sold in a package quantity of 25 units, making it practical for stocking and job-lot purchasing.
Designed as a standard NPT-threaded black steel pipe nipple for use with compatible 1/2 inch threaded fittings, valves, and couplings in black iron piping systems.
Installation is typically performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where applicable. Shut off the gas supply or depressurize the system before making any threaded connections. Apply an approved pipe thread sealant or PTFE tape rated for the intended service prior to assembly. Do not overtighten threaded connections, as this can cause damage to fittings or the nipple threads.
