Aqualine GPN-40-36 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-40-36 is a Schedule 40 galvanized steel pipe nipple measuring 4 inches in diameter by 36 inches in length. It is used to connect threaded pipe fittings in water supply, drainage, and industrial piping systems. The galvanized zinc coating provides corrosion resistance for wet and outdoor service environments. At 32.3 pounds, this is a heavy-duty, full-length nipple suited for commercial and industrial installations where a close or short nipple will not span the required distance. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

This nipple is appropriate for residential and commercial plumbing, fire protection rough-in, and mechanical room piping where Schedule 40 wall thickness is specified. It fits standard NPT threaded fittings and flanges in 4-inch pipe systems. Common applications include service water lines, irrigation manifolds, and industrial process piping where galvanized steel is the required material.

Key Features

• Schedule 40 wall thickness meets standard pressure ratings for 4-inch steel pipe
• Galvanized zinc coating resists corrosion in wet and outdoor service conditions
• 36-inch length spans longer distances than close or short nipples without additional couplings
• NPT threaded ends for direct connection to standard pipe fittings and flanges
• Heavy-duty steel construction suitable for commercial and industrial piping

Compatibility

Designed as an OEM-style replacement or new-installation component for 4-inch Schedule 40 threaded galvanized steel piping systems using standard NPT fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water or fluid supply completely before threading or removing any fittings. Apply an approved thread sealant or PTFE tape to NPT threads before assembly. Due to the 32.3-pound weight of this nipple, use appropriate lifting technique or mechanical assistance when positioning it in overhead or vertical runs.
