The ANVIL INTERNATIONAL INC 8700141404 is a black steel pipe nipple sized at 1 inch nominal diameter by 8 inches in length. Pipe nipples are short threaded pipe sections used to connect fittings, valves, and other components in piping assemblies. This nipple is manufactured from black steel, making it well suited for gas distribution, steam, and general industrial piping systems. Plumbers, pipefitters, and HVAC technicians commonly install these as close or shoulder nipples within low-pressure gas and hydronic heating installations.
This 1-inch by 8-inch black nipple is a standard fitting for residential and light commercial piping applications. It is commonly used in natural gas supply lines, propane distribution, steam systems, and fire protection headers where black steel pipe is specified. The 8-inch length provides enough extension for typical branch or riser connections without requiring an additional coupling. Pipefitters and licensed plumbers install this fitting during new construction and retrofit work.
Designed as a standard OEM-style replacement or new-install fitting for 1-inch black steel pipe systems using NPT-threaded connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas piping, or IPC requirements for other fluid systems. Shut off and depressurize the line before removing or installing any threaded fittings. Apply an appropriate thread sealant or pipe tape rated for the intended service medium. Do not overtighten threaded connections, as this can crack fittings or distort sealing surfaces.
