Value Collection NB04001 Black Steel Pipe Nipple Sch 40

Product Description

The VALUE COLLECTION NB04001 is a close-pattern black steel pipe nipple designed for use in threaded piping systems where a minimal extension between two fittings is required. Machined to Schedule 40 wall thickness and threaded to ANSI B1.20.1 and ASME B1.20.1 standards, this nipple measures 1/2 inch in diameter and 1-1/8 inches in length. It is suited for gas, water, and steam distribution lines in residential and light commercial applications. Plumbers, pipefitters, and mechanical contractors install this type of fitting when connecting valves, tees, elbows, or other threaded components in iron pipe systems.

This close nipple is a standard fitting in Schedule 40 black iron pipe assemblies. It is commonly used in natural gas supply lines, hydronic heating distribution, compressed air headers, and general plumbing rough-in work. The short body length makes it appropriate for tight-clearance installations where a longer nipple or coupling would not fit. Its black iron finish distinguishes it from galvanized fittings and is standard practice in gas piping installations per applicable codes.

Key Features

• Close nipple configuration for minimal spacing between threaded fittings
• Schedule 40 wall thickness for standard-duty pressure piping applications
• Threaded to ANSI B1.20.1 and ASME B1.20.1 standards for consistent thread engagement
• Black steel construction suitable for gas, steam, and water service
• 1/2 inch pipe size with 1-1/8 inch body length
• ASTM-compliant material specification

Compatibility

Designed as a standard close nipple for use with 1/2 inch Schedule 40 threaded black iron pipe fittings, valves, and manifolds conforming to ANSI B1.20.1 thread specifications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable code requirements, including IFGC provisions for gas piping or IPC requirements for water and steam systems. Apply a code-approved pipe thread sealant or PTFE tape to male threads before assembly. Hand-tighten first, then wrench-tighten to avoid cross-threading on this short close nipple body. Always depressurize and isolate the line section before removing or installing any threaded fitting.
