Aqualine GPN-50-36 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-50-36 is a Schedule 40 galvanized steel pipe nipple used to make threaded pipe connections in water supply, gas distribution, and general plumbing systems. At 0.5 inches nominal diameter and 36 inches in length, it provides a longer run between fittings without requiring a union or coupling. The galvanized coating provides corrosion resistance in wet and exposed environments. Licensed plumbers and pipefitters install this type of nipple in residential and commercial plumbing, fire suppression, and industrial piping assemblies where a durable, code-compliant threaded connection is required.

This nipple is suited for residential and light commercial plumbing applications where a 0.5-inch threaded connection over a longer distance is needed. Typical uses include water supply risers, gas drop lines, and compressed air distribution. The 36-inch length reduces the need for multiple fittings in straight runs and is commonly used in utility rooms, mechanical spaces, and overhead piping installations where a single long nipple simplifies the layout.

Key Features

• Schedule 40 wall thickness for standard-pressure plumbing and gas service
• Galvanized steel construction resists corrosion in wet and humid environments
• 0.5-inch nominal diameter with NPT threads on both ends for standard fitting compatibility
• 36-inch length reduces fitting count in longer straight runs
• Weighs 2.4 pounds for straightforward handling and single-person installation

Compatibility

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

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements depending on the service. Apply approved pipe thread sealant or PTFE tape to all male threads before assembly. Shut off the water or gas supply and relieve system pressure fully before cutting into any existing line. Do not over-tighten threaded connections, as this can crack fittings or strip threads on galvanized pipe.
