Value Collection NB10040 Black Steel Pipe Nipple Sch 40

Product Description

The VALUE COLLECTION NB10040 is a black steel pipe nipple designed for use in threaded pipe assemblies across plumbing, gas, and mechanical piping systems. Measuring 2.5 inches in diameter and 4 inches in length, this Schedule 40 nipple provides the wall thickness required for standard-pressure applications. Threads conform to ANSI B1.20.1 and ASME B1.20.1 standards, ensuring compatibility with standard NPT fittings. Licensed plumbers, pipefitters, and HVAC technicians install this type of nipple as a close or short extension between threaded fittings, valves, and pipe sections. The steel construction handles the mechanical and thermal demands common in black iron piping systems.

This nipple is suited for residential and light commercial applications including gas supply lines, steam systems, compressed air lines, and water distribution where black steel pipe is specified. The 4-inch length makes it a practical close nipple for tight-clearance runs or transition connections. It is sold individually and is compatible with standard 2.5-inch NPT threaded fittings and pipe components.

Key Features

• Schedule 40 wall thickness rated for standard-pressure piping applications
• Threads machined to ANSI B1.20.1 and ASME B1.20.1 NPT standards
• Steel construction suitable for gas, steam, compressed air, and water service
• 2.5-inch pipe size with 4-inch overall length for short-run or transition connections
• ASTM-referenced material standards for consistent steel quality

Compatibility

Designed as an OEM-style replacement or new-installation component for standard 2.5-inch NPT threaded piping systems using Schedule 40 black steel pipe and fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas applications, or IPC requirements for plumbing applications. Shut off the gas or fluid supply and relieve system pressure completely before threading or removing any nipple. Apply an approved thread sealant or PTFE tape rated for the service type before making up the joint. Do not overtighten threaded connections, as this can crack fittings or strip threads.
