Aqualine GPN-30-40 Galvanized Steel Nipple Sch 40

Product Description

The AQUALINE GPN-30-40 is a Schedule 40 galvanized steel pipe nipple measuring 3 inches in diameter by 4 inches in length. Galvanized steel construction provides corrosion resistance for use in wet and exposed environments. This nipple serves as a short threaded connector between pipe sections or fittings, allowing plumbers and pipefitters to close gaps in a run or extend a threaded assembly. At 1.8 pounds, the part is appropriately substantial for Schedule 40 wall thickness and standard NPT threading. It is a staple fitting in commercial and residential plumbing rough-in work.

The GPN-30-40 is suited for water supply, irrigation, fire protection headers, and general industrial piping applications where a 3-inch galvanized nipple is required. The 4-inch body length fits typical close-quarter runs where a longer nipple is not practical and a close nipple falls short. Plumbers, pipefitters, and mechanical contractors are the primary installers of this fitting type in both new construction and retrofit scenarios.

Key Features

• Schedule 40 wall thickness for pressure-rated galvanized steel pipe service
• Galvanized steel construction resists corrosion in damp and exposed installations
• 3-inch diameter by 4-inch body length suits close-quarter piping runs
• Standard NPT threads on both ends for compatibility with threaded fittings and valves
• Order increment of 1 for single-unit purchasing flexibility

Compatibility

Designed as an OEM-style replacement and standard fitting for 3-inch Schedule 40 galvanized threaded piping systems in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with the applicable plumbing code, such as the IPC or local jurisdiction requirements. Shut off and depressurize the water supply line before removing any existing fittings or nipples. Apply an approved thread sealant or PTFE tape to all NPT threads before assembly, and tighten fittings with a pipe wrench to achieve a leak-free joint without over-stressing the threads. Inspect the completed assembly for leaks after restoring system pressure.
