Edmund a Gray NIPGAL112-512 Galvanized Steel Pipe Nipple

Product Description

The EDMUND A GRAY NIPGAL112-512 is a galvanized steel pipe nipple sized at 1-1/2 inches nominal pipe diameter by 5-1/2 inches in length. Pipe nipples are short threaded pipe sections used to connect two female-threaded fittings, valves, or equipment ports in a piping system. The galvanized steel construction provides corrosion resistance suitable for water, gas, and general-purpose piping applications. Licensed plumbers, pipefitters, and HVAC mechanics install this type of fitting as part of supply and distribution piping assemblies in both new construction and retrofit work.

This nipple is suited for residential and light commercial plumbing, heating, and gas piping systems where a 1-1/2-inch NPT threaded connection is required and a close or hex nipple does not provide sufficient extension. Common applications include water supply branch connections, boiler piping, gas line assemblies, and hydronic heating distribution headers where a short rigid extension between fittings is needed.

Key Features

• Galvanized steel construction resists corrosion in water and general-purpose piping service
• 1-1/2 inches nominal pipe size with NPT-compatible male threads on both ends
• 5-1/2 inches overall length provides a short rigid extension between threaded fittings
• Suitable for water, gas, and hydronic heating piping installations

Compatibility

Designed as a standard NPT-threaded replacement or new-installation nipple for 1-1/2-inch threaded piping systems in plumbing, HVAC, and gas distribution applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the supply line before removing or installing any threaded pipe fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly and tighten fittings with pipe wrenches to a leak-free connection. For gas service, verify joint integrity with an approved leak-detection method before returning the system to service.
