The ANVIL INTERNATIONAL INC 8700140059 is a black steel pipe nipple used to connect threaded pipe sections in plumbing, HVAC, gas distribution, and industrial piping systems. Sized at 3/4 inch diameter by 5-1/2 inches in length, this close-cut nipple provides a rigid, threaded coupling point between fittings, valves, and pipe runs. Black pipe nipples are standard in low-pressure gas and steam applications where galvanized fittings are not required. Licensed plumbers, pipefitters, and mechanical contractors typically install this part as part of a larger threaded assembly.
This nipple is suited for residential and light commercial piping installations including natural gas supply lines, steam heating systems, and general-purpose black iron pipe runs. It threads directly into standard NPT-compatible fittings and pipe couplings. The 3/4 inch size is a common diameter in residential gas appliance hookups and boiler piping. It is sold in a package quantity of 25 units, making it practical for multi-unit jobs or stocking purposes.
Designed as an OEM-style replacement and standard-stock fitting for 3/4 inch NPT threaded piping systems in plumbing, mechanical, and gas distribution applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by application. Shut off the gas or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape rated for the intended service before threading. Do not over-tighten, as this can crack fittings or distort threads.
