Aqualine GPN-50-300 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-50-300 is a Schedule 40 galvanized steel pipe nipple rated for use in standard threaded piping assemblies across plumbing, HVAC, and light industrial applications. Measuring 0.5 inches in diameter and 30 inches in length, this nipple is hot-dip galvanized for corrosion resistance in wet or moderately corrosive environments. The Schedule 40 wall thickness provides the structural integrity required for typical water supply, gas distribution, and mechanical piping systems. Both ends are threaded to NPT standards, allowing direct connection to fittings, valves, and pipe unions without modification. Licensed plumbers and pipefitters are the primary installers of this component.

This nipple is suited for residential and light commercial piping runs where a longer close-to-close threaded section is needed. Common applications include water supply risers, gas piping extensions, equipment connections, and mechanical room distribution headers. The 30-inch length reduces the need for additional couplings in straight runs, simplifying installation and reducing potential leak points in the system.

Key Features

• Schedule 40 wall thickness for standard-pressure piping service
• Hot-dip galvanized steel construction resists corrosion in wet environments
• 30-inch length reduces coupling count in long straight runs
• NPT-threaded on both ends for compatibility with standard fittings and valves
• 0.5-inch nominal pipe size fits widely available fittings and hardware

Compatibility

Designed as an OEM-style threaded nipple for use with standard 0.5-inch NPT fittings, valves, and couplings in Schedule 40 galvanized steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code (IPC) or applicable local codes. Shut off and depressurize the supply line before making any threaded connections. Apply appropriate thread sealant or PTFE tape to all NPT threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
