Edmund a Gray NIPGAL112-5 Galvanized Steel Pipe Nipple

Product Description

The EDMUND A GRAY NIPGAL112-5 is a galvanized steel pipe nipple sized at 1-1/2 inches in diameter and 5 inches in length. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other piping components in a run. This nipple is manufactured from galvanized steel, providing corrosion resistance suitable for water supply, gas distribution, and general mechanical piping systems. It is a standard item installed by licensed plumbers, pipefitters, and HVAC technicians working on both new construction and retrofit projects.

This pipe nipple is suited for residential and light commercial plumbing, hydronic heating, gas piping, and similar threaded pipe assemblies. The 1-1/2-inch nominal size is common in water distribution mains, drain connections, and gas supply lines. The 5-inch length makes it appropriate for close-coupled connections where a standard close nipple or longer pipe section would not fit the application.

Key Features

• Galvanized steel construction for corrosion resistance in wet and outdoor environments
• 1-1/2 inches nominal pipe size for compatibility with standard 1-1/2-inch threaded fittings
• 5-inch overall length for short-run and offset connections
• Threaded ends allow connection to standard NPT fittings, valves, and unions
• Suitable for water supply, gas, and general mechanical piping applications

Compatibility

Designed as a standard replacement or new-installation threaded pipe nipple for use with 1-1/2-inch NPT-threaded fittings, valves, couplings, and pipe assemblies in plumbing and mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code or International Fuel Gas Code as applicable. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and tighten fittings to hand-tight plus additional turns with a pipe wrench — do not overtighten, as this can crack fittings or distort threads. Shut off and depressurize the affected water or gas line before beginning work, and test all joints for leaks after pressurizing the system.
