Aqualine GPN-250-40 Galvanized Steel Nipple Sch 40

Product Description

The AQUALINE GPN-250-40 is a Schedule 40 galvanized steel pipe nipple sized at 2.5 inches in diameter by 4 inches in length. Galvanized steel construction provides a zinc coating that resists corrosion in wet and humid environments. This nipple is a short threaded fitting used to connect two female-threaded pipe fittings, valves, or equipment ports. Plumbers, pipefitters, and mechanical contractors install nipples like this as part of water supply, drain, compressed air, and general industrial piping systems. The Schedule 40 wall thickness meets standard pressure ratings for most commercial and residential plumbing applications.

This nipple is suited for residential and light commercial plumbing installations where a short, rigid threaded connection is required. Typical uses include connecting gate valves, union fittings, hose bibbs, and equipment stubs in water supply and distribution lines. The galvanized finish makes it a practical choice for exposed or semi-exposed installations where bare steel would be vulnerable to surface rust.

Key Features

• Schedule 40 wall thickness for standard plumbing pressure service
• Hot-dip galvanized zinc coating for corrosion resistance in wet environments
• 2.5-inch nominal pipe size with 4-inch overall length
• Male NPT threads on both ends for standard pipe fitting connections
• Compatible with Schedule 40 fittings, valves, and couplings of matching size

Compatibility

Designed as an OEM-style replacement or standard installation fitting for Schedule 40 threaded piping systems using 2.5-inch nominal pipe size components.

Installation Notes

Installation is performed by licensed plumbers or pipefitters using pipe wrenches and appropriate thread sealant or PTFE tape applied to the male threads. Shut off the water supply and depressurize the line before removing or installing any threaded pipe fitting. Follow local plumbing codes and IPC requirements for approved materials and joint compounds in potable water systems. Do not overtighten threaded connections, as this can crack fittings or distort threads.
