Anvil International Inc 8700139903 Black Pipe Nipple

Product Description

The ANVIL INTERNATIONAL INC 8700139903 is a black steel pipe nipple measuring 0.75 inches in diameter by 4 inches in length. Pipe nipples are short threaded sections of pipe used to connect two fittings, valves, or other threaded pipe components in a run. This nipple is finished in black, which is standard for natural gas, propane, and general-purpose piping systems. Licensed plumbers, pipefitters, and gas technicians install these as part of rough-in and service work on low-pressure pipe assemblies. The 4-inch length suits close-quarter connections where a longer spool piece is not needed.

Black pipe nipples like the 8700139903 are commonly used in residential and light commercial gas distribution lines, fire suppression headers, steam and hot-water heating systems, and general industrial piping. They are suitable for applications where a non-galvanized black iron or steel fitting is specified by code or system design. This nipple ships in a package quantity of 25 units, making it practical for contractors stocking vans or completing multi-connection rough-in jobs.

Installation Notes

Installation of black pipe nipples on gas lines must be performed by a licensed plumber or gas technician in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off and verify zero pressure at the gas supply or system line before making or breaking any threaded connections. Apply an approved pipe thread sealant or tape rated for the specific service medium before assembly. Do not overtighten threaded connections, as this can damage threads or cause fitting failure.
