Value Collection MSCNB01045 Black Steel Pipe Nipple

Product Description

The VALUE COLLECTION MSCNB01045 is a black steel pipe nipple designed for use in threaded pipe assemblies across plumbing, HVAC, and industrial piping systems. Built to Schedule 40 specifications with a welded construction, this nipple measures 0.125 inches in nominal pipe diameter and 4.5 inches in length. It features male NPT (MNPT) threads on both ends for straightforward connection to standard threaded fittings, valves, and pipe sections. Licensed plumbers and pipefitters rely on parts like this for low-pressure gas, water, and general service applications where a short, rigid nipple is needed to close gaps between fittings.

This nipple is suited for residential and light commercial piping installations where Schedule 40 steel and black iron fittings are standard. Common applications include natural gas distribution lines, steam systems, compressed air runs, and general water service connections. It is a close nipple alternative for runs requiring a defined 4.5-inch standoff between two threaded components. The black finish is typical for gas piping where galvanized coatings are not permitted by code.

Key Features

• Schedule 40 wall thickness for standard-service pressure ratings
• Welded steel construction for consistent dimensional integrity
• MNPT x MNPT threading on both ends for universal fitment with standard threaded fittings
• Black finish suitable for gas piping applications per common code requirements
• Nominal 0.125-inch pipe size with 4.5-inch body length

Compatibility

Designed as an OEM-style replacement or new-installation component compatible with standard 0.125-inch NPT threaded fittings, valves, and pipe couplings used in Schedule 40 black iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Shut off the gas or water supply and relieve system pressure completely before threading any nipple into an existing line. Use an appropriate thread sealant or PTFE tape rated for the service medium. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
