Aqualine GPN-125-C Galvanized Steel Close Nipple 1-1/4 in Sch 40

Product Description

The AQUALINE GPN-125-C is a 1-1/4 inch Schedule 40 close nipple machined from galvanized steel. A close nipple is threaded end-to-end with no unthreaded center section, making it the shortest possible threaded connector between two fittings. This nipple is used to create tight back-to-back connections in pipe assemblies across plumbing, HVAC, and pool and spa systems. At 0.2 pounds, it is lightweight and easy to handle during installation. Licensed plumbers and pipefitters specify Schedule 40 galvanized nipples where corrosion resistance and standard wall thickness are both required.

This close nipple is suited for residential and commercial piping applications where space between fittings is minimal. Common scenarios include connecting valves, unions, tees, and elbows in water supply lines, hydronic heating distribution systems, and pool equipment manifolds. The galvanized coating provides a zinc layer that resists rust in wet or humid service environments. It is appropriate for use in both above-ground and exposed indoor piping assemblies where threaded steel pipe is specified.

Key Features

• Close pattern threading runs end-to-end with no bare center, minimizing installed length between fittings
• Schedule 40 wall thickness meets standard pressure and mechanical strength requirements for threaded steel pipe
• Hot-dip or mill galvanized finish provides zinc corrosion protection for wet service environments
• 1-1/4 inch nominal pipe size fits standard NPT fittings and valves of the same size
• Lightweight at 0.2 pounds, easing handling in tight installation spaces

Compatibility

Designed as an OEM-style replacement and standard-stock close nipple compatible with 1-1/4 inch NPT threaded fittings, valves, and pipe couplings in Schedule 40 galvanized steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before removing or installing any threaded pipe component. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and tighten with a pipe wrench to a secure, leak-free engagement. Do not over-torque, as this can crack adjacent cast fittings or damage threads.
