Aqualine GPN-125-36 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-125-36 is a Schedule 40 galvanized steel pipe nipple measuring 1.25 inches in diameter and 36 inches in length. It is used to create threaded pipe connections in water supply, gas distribution, and general industrial piping systems. The hot-dip galvanized coating provides corrosion resistance for both indoor and outdoor installations. Plumbers and pipefitters install this nipple as a close or extension fitting between threaded pipe sections, valves, and fittings. At 6.4 pounds, the nipple is sized for demanding applications where a longer run of threaded pipe is required without welding or flanged joints.

This nipple is well suited for residential and light commercial plumbing, irrigation distribution lines, fire protection rough-in, and industrial fluid transfer. The 36-inch length makes it a practical choice when a single threaded section needs to bridge a longer span between fittings or equipment connections. The Schedule 40 wall thickness meets standard pressure requirements for typical potable water and gas service applications.

Key Features

• Schedule 40 wall thickness for standard-pressure pipe service
• Galvanized steel construction provides corrosion resistance in wet and outdoor environments
• 1.25-inch nominal diameter with standard NPT threads on both ends
• 36-inch length suits long-span connections without field cutting or welding
• Compatible with standard NPT fittings, valves, and couplings

Compatibility

Designed as a standard NPT-threaded replacement or extension nipple for use with Schedule 40 galvanized steel pipe systems and compatible threaded fittings in plumbing, gas, and industrial piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IPC, and IFGC requirements. Shut off the water or gas supply and relieve system pressure before disassembling any threaded connections. Apply an appropriate thread sealant or PTFE tape to the NPT threads before making up the joint. Do not over-torque threaded connections, as this can damage threads or crack fittings.
