Aqualine GPN-50-12 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-50-12 is a Schedule 40 galvanized steel pipe nipple sized at 0.5 inches nominal diameter by 12 inches in length. It delivers a threaded, corrosion-resistant connection point in water supply, gas distribution, and general plumbing systems. The hot-dip galvanized coating protects the steel against rust and oxidation in wet or humid environments. Both ends are threaded for standard NPT fittings, making assembly straightforward. Licensed plumbers and pipefitters use this nipple to extend or offset pipe runs in commercial and residential installations where steel piping is required or preferred.

This nipple is suited for residential and light commercial plumbing, HVAC hydronic systems, fire suppression risers, and industrial supply lines where Schedule 40 wall thickness is specified. The 12-inch length covers common offset and extension applications without requiring field-cut threading. It performs reliably in water service, air lines, and low-pressure gas piping where galvanized steel is an acceptable material per local code.

Key Features

• Schedule 40 wall thickness provides code-compliant strength for standard pressure applications
• Galvanized steel construction resists corrosion in wet and humid environments
• NPT threads on both ends ensure compatibility with standard pipe fittings and valves
• 12-inch length handles common offset and extension runs without field threading
• 0.5-inch nominal diameter fits standard half-inch piping systems

Compatibility

Designed as a standard-duty replacement or new-install nipple for 0.5-inch NPT Schedule 40 galvanized steel pipe systems in plumbing, HVAC, and light industrial applications.

Installation Notes

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