Aqualine GPN-40-24 Galvanized Steel Nipple Sch 40

Product Description

The AQUALINE GPN-40-24 is a Schedule 40 galvanized steel pipe nipple measuring 4 inches in diameter by 24 inches in length. Galvanized steel construction provides corrosion resistance suited to water supply, industrial, and mechanical piping systems. This nipple serves as a threaded connector between pipe sections, fittings, or valves, and is installed by licensed plumbers and pipefitters in both commercial and residential applications. At 21.5 pounds, it is a heavy-duty component appropriate for high-demand piping runs where durability and pressure integrity are required.

This nipple is commonly used in water distribution, fire protection, HVAC hydronic systems, and general industrial plumbing. The 4-inch diameter makes it appropriate for larger-diameter branch lines and main supply runs. It is threaded on both ends per standard NPT configuration, allowing straightforward connection to compatible schedule 40 fittings, flanges, and valves. Plumbers and mechanical contractors typically specify this size for commercial building services and municipal water applications.

Key Features

• Schedule 40 wall thickness rated for standard working pressures in steel pipe systems
• Galvanized finish provides corrosion resistance for water and moisture-exposed environments
• 4-inch diameter suits larger-diameter commercial and industrial piping runs
• 24-inch length reduces the need for additional couplings in longer straight runs
• Threaded ends allow direct connection to NPT-compatible fittings and valves

Compatibility

Designed as an OEM-style replacement and standard-stock nipple for Schedule 40 galvanized steel piping systems using 4-inch NPT threaded fittings, valves, and couplings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing code requirements. Shut off and depressurize the water supply line fully before removing existing fittings or threading on the new nipple. Apply thread sealant tape or pipe compound to the male NPT threads before tightening. Use appropriate pipe wrenches sized for 4-inch pipe to achieve a proper seal without over-stressing the threads.
