The ANVIL INTERNATIONAL INC 8700138004 is a black steel pipe nipple measuring 3/8 inch in diameter and 6 inches in length. Pipe nipples are short sections of threaded pipe used to connect two fittings, valves, or other pipe sections in a piping assembly. This nipple is finished in black, indicating it is plain steel without galvanizing, which is the standard choice for gas distribution lines, steam systems, and general-purpose piping. Licensed plumbers and pipefitters install these fittings as part of rough-in and service work across residential and light commercial applications.
This nipple is suited for gas piping, compressed air lines, steam lines, and general black iron piping systems in residential and commercial settings. The 3/8-inch diameter is a common size used in branch lines and low-flow supply runs. It is sold in packages of 25 units, making it a practical stocking item for contractors and service shops that regularly work with threaded black iron pipe assemblies.
Designed as a standard threaded black iron pipe nipple for use with 3/8-inch NPT fittings, valves, and couplings in gas, steam, and general-purpose piping systems.
Installation is performed by licensed plumbers or pipefitters following applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off the gas or fluid supply and relieve system pressure before making any threaded connections. Apply an approved thread sealant or PTFE tape rated for the intended service to all male threads before assembly. Do not over-tighten threaded connections, and inspect for leaks after restoring system pressure.
