Aqualine GPN-50-18 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-50-18 is a Schedule 40 galvanized steel pipe nipple sized at 0.5 inches nominal diameter by 18 inches in length. Galvanized steel construction provides corrosion resistance suitable for water supply, gas distribution, and general industrial piping applications. The threaded ends conform to standard NPT specifications, allowing direct connection to fittings, valves, and other threaded pipe components. At 1.2 pounds, this nipple is a straightforward, durable close-length fitting used by licensed plumbers, pipefitters, and HVAC technicians when assembling or extending threaded pipe systems.

This nipple is commonly used in residential and light commercial plumbing and mechanical systems where a 0.5-inch threaded galvanized steel connection is required. Typical applications include water supply rough-in, gas line extensions, boiler connections, and pool or spa equipment plumbing. Schedule 40 wall thickness meets standard pressure ratings for these service environments. It is well-suited for above-ground and concealed installations where NPT-threaded galvanized fittings are specified.

Key Features

• Schedule 40 wall thickness for standard pressure service in plumbing and mechanical systems
• Hot-dip or mill galvanized steel construction for corrosion resistance in water and gas service
• 0.5-inch nominal diameter with NPT-threaded ends for compatibility with standard fittings and valves
• 18-inch length provides a longer extension reach between fittings or equipment connections
• Lightweight at 1.2 pounds for easy single-handed handling during installation

Compatibility

Designed as an OEM-style replacement and standard-stock fitting for threaded 0.5-inch Schedule 40 galvanized pipe systems using NPT connections.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with the International Plumbing Code or International Fuel Gas Code, depending on the service medium. Shut off and depressurize the supply line completely before disassembling or extending any threaded pipe assembly. Apply an appropriate thread sealant or PTFE tape rated for the intended service (water or gas) to the male threads before making up the joint. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
