Aqualine GPN-75-36 Galvanized Steel Nipple Sch 40

Product Description

The AQUALINE GPN-75-36 is a Schedule 40 galvanized steel pipe nipple measuring 0.75 inches in diameter and 36 inches in length. It is used to connect sections of threaded pipe in water supply, gas, and general plumbing systems. The hot-dip galvanized coating provides corrosion resistance suitable for wet and mildly corrosive environments. At 3.2 pounds, this nipple is a full-length threaded fitting intended for permanent, load-bearing pipe runs. Licensed plumbers and pipefitters install this type of nipple in both new construction and retrofit applications across residential and light commercial settings.

This nipple is suited for use in water distribution, compressed air lines, gas piping, and fire protection systems where Schedule 40 wall thickness and galvanized protection are required. The 36-inch length makes it appropriate for spanning longer distances between fittings without adding a union or coupling mid-run. It is commonly installed in mechanical rooms, utility areas, and exposed overhead pipe runs where corrosion resistance and structural integrity matter.

Key Features

• Schedule 40 wall thickness for standard-duty pressure service
• Galvanized steel construction resists corrosion in wet and humid environments
• 0.75-inch nominal diameter with threaded ends for direct connection to standard fittings
• 36-inch length suitable for longer pipe spans without intermediate couplings
• 3.2-pound weight reflects full-length solid steel construction

Compatibility

Designed as an OEM-style replacement and standard fitment for 0.75-inch Schedule 40 threaded galvanized steel piping systems using NPT-compatible fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply or isolate the gas line and depressurize the system before threading or removing any fittings. Apply an appropriate pipe thread sealant or PTFE tape to all male threads before assembly. Do not over-torque threaded connections, as this can crack fittings or damage threads.
