Aqualine GPN-40-48 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-40-48 is a Schedule 40 galvanized steel pipe nipple measuring 4 inches in diameter by 48 inches in length and weighing 43.1 pounds. It is manufactured from steel with a hot-dip or mill-applied galvanized coating that resists corrosion in wet and outdoor piping environments. This nipple serves as a straight threaded connector between pipe fittings, valves, and equipment in water supply, industrial, and mechanical systems. Licensed plumbers and pipefitters are the primary installers, though irrigation and pool contractors also work with galvanized steel nipples of this size regularly.

This nipple is suited for residential and commercial plumbing, water distribution, and mechanical piping applications where a longer close or run-length connection is required. The 48-inch body length accommodates spans between fittings that shorter nipples cannot cover. Its Schedule 40 wall thickness meets standard pressure ratings for general water service piping. It is commonly installed in above-ground and exposed piping runs, pump discharge lines, and equipment connections in pool mechanical rooms and similar service environments.

Key Features

• Schedule 40 wall thickness for standard-service pressure ratings
• Galvanized steel construction for corrosion resistance in wet environments
• 4-inch nominal diameter for high-flow water service and mechanical piping
• 48-inch body length suits longer span connections between fittings or equipment
• Threaded ends for connection to standard NPT fittings and valves

Compatibility

Designed as a standard-thread galvanized steel nipple for use with 4-inch NPT fittings, couplings, and valves in Schedule 40 piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the supply line completely before making any threaded connections. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or damage thread integrity.
