Value Collection MSCNB05035 Black Steel Pipe Nipple

Product Description

The VALUE COLLECTION MSCNB05035 is a black steel pipe nipple used to connect threaded pipe sections in plumbing, HVAC, gas distribution, and industrial piping systems. It measures 3/4 inch in diameter and 3-1/2 inches in length, manufactured to Schedule 40 wall thickness from welded steel construction. Both ends are threaded male NPT (MNPT) for direct engagement with female-threaded fittings, valves, or pipe couplings. The black finish is standard for non-potable applications such as natural gas and propane lines. Licensed plumbers and pipefitters are the primary installers in both residential and commercial settings.

This nipple is suited for residential and light commercial piping runs where a short close-coupled connection is needed between two threaded components. Common applications include gas line drops, boiler trim piping, steam system connections, and general black iron pipe assemblies. The 3/4 inch nominal size is one of the most common in residential gas and hydronic heating systems. Schedule 40 wall thickness meets standard pressure-service requirements for these installations.

Key Features

• Schedule 40 wall thickness for standard-pressure piping service
• Welded steel construction provides consistent dimensional accuracy
• MNPT x MNPT threading on both ends for direct connection to standard female-threaded fittings
• Black finish appropriate for gas, steam, and non-potable water applications
• 3/4 inch nominal diameter, one of the most widely used sizes in residential and commercial piping
• 3-1/2 inch length for short close-coupled connections where space is limited

Compatibility

Designed as a standard-thread replacement or new-installation nipple compatible with 3/4 inch female NPT fittings, valves, tees, elbows, and couplings used in Schedule 40 black iron pipe systems.

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) depending on the service. Apply an approved thread sealant or PTFE tape rated for the intended service medium before engagement. Shut off and depressurize the line completely before removing any existing fittings or nipples. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
