The ANVIL INTERNATIONAL INC 8700144556 is a black steel pipe nipple sized at 2 inches by 3 inches, used to create threaded connections between fittings, valves, and pipe sections in fluid and gas distribution systems. Black pipe nipples are a standard component in low-pressure steam, gas supply, and water distribution piping. This nipple is sold in packages of 25 units, making it practical for contractors and service technicians who need to stock fittings on the truck or at the shop. The 3-inch length suits close-coupled connections where a full pipe run is not required.
Black pipe nipples of this type are commonly installed in residential and light commercial gas piping systems, including natural gas and propane supply lines to appliances such as furnaces, boilers, water heaters, and ranges. They are also used in fire sprinkler rough-in work and low-pressure steam systems. Plumbers and pipefitters install these fittings as part of threaded iron pipe assemblies wherever a short, rigid connection between two threaded components is needed.
Designed as a standard replacement or new-installation fitting compatible with 2-inch NPT threaded pipe systems in residential and commercial gas, steam, and water piping applications.
Black pipe nipples are installed by licensed plumbers or pipefitters in accordance with local mechanical and fuel gas codes, including IFGC and IPC requirements. Shut off the gas or water supply and verify zero pressure at the line before breaking any threaded connection. Apply an approved thread sealant or PTFE tape rated for the specific service medium before tightening. Inspect threads for damage before installation and do not over-tighten, as this can crack fittings or distort seating surfaces.
