Aqualine GPN-40-60 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-40-60 is a Schedule 40 galvanized steel pipe nipple sized at 4 inches nominal diameter by 6 inches in length. Galvanized steel construction provides corrosion resistance suitable for water supply, gas distribution, and general plumbing applications. This nipple serves as a threaded connector between fittings, valves, and other pipe components in both above-ground and certain below-ground configurations. Licensed plumbers and pipefitters are the primary installers, though pool and irrigation technicians also work with nipples of this specification regularly.

This nipple is well suited for residential and light commercial plumbing systems where a short, threaded steel connection is required between flanges, unions, valves, or tees. The 4-inch nominal diameter and 6-inch length make it a common choice in larger pipe runs found in mechanical rooms, boiler rooms, and municipal-style water service entries. Pool and spa equipment rooms with steel pipe infrastructure are another typical application.

Key Features

• Schedule 40 wall thickness for standard-service pressure ratings
• Hot-dip galvanized coating for corrosion and rust resistance
• 4-inch nominal diameter with 6-inch overall length
• Threaded ends for connection to standard NPT fittings and valves
• Suitable for water supply, gas, and general plumbing service

Compatibility

Designed as an OEM-style replacement or standard-service nipple compatible with Schedule 40 NPT threaded fittings and valves in 4-inch nominal pipe size systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code. Shut off the water or gas supply and depressurize the line completely before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
