Aqualine GPN-250-C 2.5 in Close Sch 40 Galvanized Nipple

Product Description

The AQUALINE GPN-250-C is a 2.5-inch close-pattern Schedule 40 galvanized steel pipe nipple used in threaded piping systems across plumbing, HVAC, and industrial applications. A close nipple has fully threaded ends that meet at the center, allowing two fittings to be joined with minimal gap between them. The Schedule 40 wall thickness provides reliable pressure-rated performance, and the hot-dip galvanized finish resists corrosion in wet or exposed environments. Licensed plumbers and pipefitters install this type of nipple when assembling or repairing threaded iron pipe runs.

This nipple is suited for residential and light commercial piping installations where a close-coupled threaded connection is required. Common applications include water supply lines, gas distribution piping (where code-approved for galvanized steel), hydronic heating systems, and general-purpose iron pipe assemblies. It is installed wherever a short, fully threaded male-to-female connection is needed to close the gap between two fittings or valves.

Key Features

• Close-pattern design — fully threaded end-to-end for minimum installed length
• Schedule 40 wall thickness for standard-duty pressure-rated service
• Galvanized steel construction resists corrosion in damp and wet environments
• 2.5-inch nominal pipe size fits standard NPT threaded fittings and valves
• Order increment of 1 — sold individually

Compatibility

Designed as an OEM-style replacement or direct addition to standard 2.5-inch NPT threaded iron pipe systems using Schedule 40 fittings, valves, and couplings.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the pipe system completely before removing or installing any threaded nipple. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and tighten with a pipe wrench to a snug, leak-free fit. Do not over-torque close nipples, as the short threaded body leaves limited material between threads.
