Anvil International Inc 8700138400 Black Pipe Nipple

Product Description

The ANVIL INTERNATIONAL INC 8700138400 is a black steel pipe nipple sized at 1/2 inch nominal diameter by 1-1/2 inches in length. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or threaded ports in a piping system. This nipple ships in a package quantity of 25 units, making it well suited for contractors and service professionals stocking common fittings for residential or commercial plumbing, gas, or mechanical installations. The black finish is standard for natural gas and propane supply lines as well as steam and hydronic heating systems. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this fitting type.

This nipple is appropriate for use in residential and light commercial piping systems where a 1/2-inch threaded connection is required. Common applications include natural gas branch lines, propane distribution piping, steam heating systems, hydronic heating loop connections, and general black iron plumbing assemblies. The 1-1/2-inch close-to-short length makes it useful in tight spaces where a standard-length nipple would not fit. It is commonly used alongside black iron tees, elbows, unions, and valves.

• 1/2-inch nominal diameter with standard NPT male threads on both ends
• 1-1/2-inch overall length for use in compact or tight installation spaces
• Black steel finish suitable for natural gas, propane, steam, and hydronic systems

Compatibility

Installation Notes

Installation of black iron pipe nipples should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with local plumbing and mechanical codes, including IFGC requirements for gas piping. Always shut off the gas supply or isolate the water or steam system and relieve pressure before disassembling or extending any piping. Apply an approved thread sealant or PTFE tape rated for the intended service medium before threading the nipple into fittings. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
