Aqualine GPN-125-60 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-125-60 is a Schedule 40 galvanized steel pipe nipple sized at 1-1/4 inches nominal diameter by 6 inches in length. Galvanized steel construction provides corrosion resistance suitable for water supply, gas distribution, and general plumbing applications. The threaded ends conform to standard NPT specifications, allowing direct connection to fittings, valves, and pipe sections of matching size. Licensed plumbers and pipefitters install this type of nipple in both residential and light commercial systems. The Schedule 40 wall thickness meets standard pressure ratings for typical plumbing and low-pressure gas service.

This nipple is used in water supply lines, drain and vent assemblies, fire suppression risers, compressed air distribution, and low-pressure gas piping where galvanized steel is the specified material. It is a common component in commercial mechanical rooms, residential utility spaces, and industrial process piping where threaded steel connections are required. The 6-inch length makes it suitable for close-quarter connections and short-run extensions between fittings.

Key Features

• Schedule 40 wall thickness for standard-service pressure ratings
• Hot-dip galvanized coating provides corrosion and rust resistance
• 1-1/4 inch nominal diameter with NPT-threaded ends on both sides
• 6-inch overall length for short-run and close-quarter installations
• Compatible with standard NPT fittings, couplings, and valves

Compatibility

Designed as a standard NPT-threaded replacement or new-installation nipple for use with Schedule 40 galvanized or black steel pipe systems using 1-1/4 inch fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the IPC and IFGC where gas service is involved. Apply an approved thread sealant or PTFE tape to all male NPT threads before assembly. Use a pipe wrench on the body of the nipple rather than on the threads to avoid deformation. Always verify pressure ratings and material compatibility with the system fluid or gas before installation.
