Value Collection MSCNB04045 Black Pipe Nipple 1/2x4.5 Sch40

Product Description

The VALUE COLLECTION MSCNB04045 is a Schedule 40 black steel pipe nipple used to connect threaded pipe sections in gas, water, and general plumbing systems. Measuring 1/2 inch in diameter and 4.5 inches in length, it is welded construction with male NPT threads on both ends. The black iron finish is standard for gas distribution lines and low-pressure steam applications. Plumbers, pipefitters, and HVAC technicians install this nipple as a short extension or connector between fittings, valves, and pipe runs where a close nipple is too short and a longer run is not required.

This nipple is suited for residential and light commercial installations including natural gas and propane supply lines, black iron pipe assemblies, and general-purpose threaded pipe systems. Its Schedule 40 wall thickness meets standard pressure requirements for typical trade applications. It is commonly used in boiler rooms, mechanical rooms, and utility connections where black iron pipe is the specified material.

Key Features

• Schedule 40 wall thickness for standard-pressure threaded pipe systems
• Welded steel construction for consistent wall integrity along the length
• Male NPT threads on both ends for compatibility with standard threaded fittings and valves
• Black iron finish appropriate for gas line and low-pressure steam service
• 1/2 inch pipe size fits common residential and light commercial pipe runs

Compatibility

Designed as a standard 1/2 inch Schedule 40 MNPT x MNPT black steel pipe nipple compatible with any threaded black iron pipe system using 1/2 inch NPT fittings, valves, and connectors.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by the application. Shut off the gas or water supply and depressurize the line before removing or installing any threaded pipe component. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium before threading the nipple into fittings. Do not overtighten threaded connections, as this can crack fittings or distort threads.
