Aqualine GPN-20-18 Galvanized Steel Nipple 2x18 Sch 40

Product Description

The AQUALINE GPN-20-18 is a Schedule 40 galvanized steel pipe nipple measuring 2 inches in diameter by 18 inches in length. It serves as a threaded connector used to join pipe fittings, valves, and equipment in water supply, industrial, and mechanical piping systems. The hot-dip galvanized zinc coating provides corrosion resistance in wet and exposed environments. This nipple is sized for standard 2-inch NPT threaded connections and is suited for plumbing, HVAC hydronic piping, and general-purpose pipe assembly work performed by licensed plumbers and mechanical contractors.

This nipple is used in residential and commercial plumbing and mechanical systems where a 2-inch threaded connection is required. Common applications include water supply distribution, drain and vent assemblies, fire suppression rough-in, and hydronic heating piping. The 18-inch length accommodates installations that require a longer close nipple run between fittings or across a short span in a pipe rack or mechanical room layout.

Key Features

• Schedule 40 wall thickness for standard-pressure service in water and mechanical piping
• Galvanized steel construction provides corrosion resistance in wet and exposed environments
• 2-inch NPT threads on both ends for compatibility with standard threaded fittings and valves
• 18-inch body length suitable for spanning short offsets in pipe runs
• Weighs 5 pounds for straightforward handling and installation

Compatibility

Designed as an OEM-style threaded pipe nipple for use with standard 2-inch NPT fittings, couplings, valves, and pipe flanges in Schedule 40 galvanized steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor in accordance with applicable IPC and local plumbing code requirements. Apply a rated pipe thread sealant or PTFE tape to the male NPT threads before assembly to ensure a leak-free joint. Use a pipe wrench sized for 2-inch pipe and avoid over-tightening, which can crack fittings. Shut off and depressurize the water or fluid supply before cutting into any existing piping.
