Aqualine GPN-30-12 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-30-12 is a Schedule 40 galvanized steel pipe nipple measuring 3 inches in diameter by 12 inches in length. Galvanized steel construction provides corrosion resistance suited for water supply, industrial, and general plumbing distribution systems. The hot-dip galvanized coating protects the base steel from rust and oxidation in both wet and dry environments. This nipple serves as a short threaded connector between fittings, valves, and threaded pipe ends. Licensed plumbers and pipefitters install these components in commercial and residential systems where a durable, threaded steel connection is required.

This nipple is used in water supply lines, irrigation systems, fire protection piping, and general industrial plumbing applications. The 3-inch diameter and 12-inch length make it appropriate for larger-diameter distribution runs where a close or extension connection is needed between threaded components. It is suitable for above-ground and certain below-grade installations depending on local code requirements and corrosion exposure conditions.

Key Features

• Schedule 40 wall thickness rated for standard working pressures in plumbing and industrial applications
• Galvanized steel construction resists corrosion and extends service life in wet environments
• 3-inch diameter by 12-inch length for larger-diameter threaded connections
• Male NPT threads on both ends for direct connection to fittings, valves, and couplings
• Weighs 6.7 pounds for solid, heavy-duty construction

Compatibility

Designed as a standard Schedule 40 galvanized steel threaded nipple compatible with 3-inch NPT fittings, couplings, and valves used in residential and commercial plumbing and industrial piping systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before removal or installation of any threaded pipe component. Apply thread sealant tape or pipe dope to the male NPT threads before assembly to ensure a leak-free connection. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
