Aqualine GPN-40-18 Galvanized Steel Nipple Sch 40 4x18 in

Product Description

The AQUALINE GPN-40-18 is a Schedule 40 galvanized steel pipe nipple measuring 4 inches in diameter by 18 inches in length. Galvanized steel construction provides corrosion resistance suited for water supply, irrigation, and general plumbing distribution systems. This nipple serves as a threaded connector between pipe fittings, valves, and other plumbing components. Plumbers and pipefitters install this type of close-tolerance nipple when a rigid, durable, corrosion-resistant connection is required in ferrous piping systems. At 16.1 pounds, this is a heavy-duty fitting intended for sustained service in demanding pipe assemblies.

This nipple is appropriate for residential and light commercial plumbing installations where galvanized steel pipe is the specified material. Common applications include water distribution lines, fire protection rough-in, industrial supply runs, and pool or irrigation system piping. Its Schedule 40 wall thickness makes it suitable for standard working pressures encountered in typical building service water systems. Licensed plumbers and pipe trade professionals are the primary installers of this fitting.

Key Features

• Schedule 40 wall thickness for standard service pressure ratings in water supply applications
• Galvanized steel construction resists corrosion in wet and humid environments
• 4-inch diameter by 18-inch length for longer-reach threaded connections
• Threaded ends for direct connection to compatible galvanized or black iron fittings and valves
• Heavy-duty construction at 16.1 pounds suitable for sustained service loads

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 galvanized steel pipe systems using 4-inch threaded connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and depressurize the line before removing or installing any threaded fitting. Use an appropriate pipe thread sealant or PTFE tape on all male threads before assembly. Do not over-torque threaded connections, as this can damage threads or crack adjacent fittings.
