Anvil International Inc 8700139853 Black Pipe Nipple

Product Description

The ANVIL INTERNATIONAL INC 8700139853 is a black steel pipe nipple sized at 3/4 inch diameter by 3-1/2 inches in length. Pipe nipples are short sections of externally threaded pipe used to connect fittings, valves, and other piping components in a run. This nipple ships in a package quantity of 25 units, making it practical for jobs requiring multiple connections. The black finish indicates an uncoated steel construction typical of gas and low-pressure fluid distribution systems. Plumbers, pipefitters, and HVAC technicians regularly install this type of fitting in both new construction and retrofit work.

This nipple is suited for residential and light commercial piping applications including natural gas distribution, steam heating systems, and general-purpose low-pressure pipe assemblies. The 3/4 inch thread size is one of the most common sizes in residential gas rough-in and boiler piping. The 3-1/2 inch length provides enough extension between fittings where close or hex nipples are too short but a longer nipple would create unnecessary run. It is commonly installed in conjunction with black malleable iron fittings, valves, and unions.

Key Features

• 3/4 inch nominal diameter with 3-1/2 inch overall length for precise fit in tight runs
• Black steel construction standard for gas and steam piping applications
• External NPT threads on both ends for connection to standard pipe fittings and valves
• Sold in a package quantity of 25 for multi-connection jobs

Compatibility

Designed as an OEM-style replacement and standard-use fitting compatible with 3/4 inch NPT threaded black malleable iron and steel pipe systems used in gas, steam, and general low-pressure fluid distribution.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, IFGC requirements for gas piping, or ASME B31 standards for pressure piping. Shut off gas or fluid supply and verify zero pressure in the line before removing or installing any fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all NPT threads before assembly. Do not over-torque threaded connections, as this can crack fittings or distort threads.
