The ANVIL INTERNATIONAL INC 8700141008 is a black steel pipe nipple measuring 1 inch in diameter by 3 inches in length. Pipe nipples are short sections of threaded pipe used to connect fittings, valves, and other components in a piping system. This nipple is finished in black, indicating an uncoated carbon steel construction typical for gas, steam, and industrial fluid applications. Plumbers, pipefitters, and HVAC technicians commonly install this type of nipple when assembling or repairing threaded piping systems in both residential and light commercial environments.
The 1-inch by 3-inch black nipple is suited for threaded piping assemblies in natural gas, propane, steam, and air distribution systems. Its compact 3-inch length makes it well suited for close-quarter connections where a longer nipple or standard pipe section would not fit. It is typically found in mechanical rooms, boiler connections, gas train assemblies, and industrial process lines where black steel pipe is the specified material.
Designed as a standard NPT-threaded black steel pipe nipple for use with 1-inch threaded fittings, valves, and couplings in residential and commercial gas, steam, and air piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off the gas or fluid supply and relieve system pressure before beginning any threaded pipe assembly or disassembly. Apply an approved thread sealant or PTFE tape rated for the intended service medium to all threaded connections. Do not over-tighten threaded connections, as this can damage fittings or compromise the seal.
