Aqualine GPN-30-80 Galvanized Steel Nipple Sch 40 3x8

Product Description

The AQUALINE GPN-30-80 is a Schedule 40 galvanized steel pipe nipple sized at 3 inches by 8 inches. It is a short threaded pipe section used to connect two female-threaded fittings, valves, or equipment ports in water supply, heating, and industrial piping systems. The galvanized zinc coating provides corrosion resistance in wet and high-humidity environments. At 4.12 pounds, this is a robust, full-weight fitting suited for permanent installation in commercial and residential piping. Licensed plumbers and pipefitters are the primary installers for this type of component.

This nipple is appropriate for use in water distribution lines, boiler systems, hydronic heating loops, and general industrial plumbing applications where Schedule 40 wall thickness is specified. It is commonly installed in locations requiring a short extension between threaded components. The 3-inch diameter makes it a larger trade-size fitting typical of commercial plumbing, light industrial, and mechanical room installations rather than standard residential fixture work.

Key Features

• Schedule 40 wall thickness rated for standard working pressures in commercial and residential piping
• Hot-dip galvanized zinc coating resists corrosion in wet, damp, and outdoor environments
• 3-inch nominal diameter suitable for high-flow commercial and industrial piping runs
• 8-inch body length provides adequate extension between threaded fittings or equipment ports
• Threaded ends conform to standard NPT threading for broad fitting compatibility

Compatibility

Designed as an OEM-style replacement and standard-use nipple for Schedule 40 threaded galvanized steel piping systems using 3-inch NPT connections.

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 water or fluid system fully before removing or installing any threaded nipple. Apply an approved thread sealant or PTFE tape to the male NPT threads before making up the joint. Do not over-torque threaded connections, as this can crack fittings or distort threads.
