The AQUALINE GPN-20-80 is a Schedule 40 galvanized steel pipe nipple measuring 2 inches in diameter by 8 inches in length. Galvanized steel construction provides corrosion resistance, making this nipple suitable for water supply, plumbing distribution, and general industrial piping applications. The threaded ends allow for direct connection to standard NPT fittings, valves, and couplings. Licensed plumbers and pipefitters install this type of nipple as a short run connector between fittings or equipment in both above-ground and exposed piping systems. At 2.15 pounds, it is a solid, full-weight Schedule 40 fitting appropriate for standard service pressure ratings.
This pipe nipple is used in residential and commercial plumbing systems where a short threaded galvanized steel connector is required. Common applications include water supply lines, fire protection risers, irrigation headers, and industrial fluid transfer systems. The galvanized coating helps resist rust and corrosion in wet environments. It is well suited for exposed or mechanical room installations where metal pipe is preferred over plastic alternatives.
Designed as a standard Schedule 40 galvanized steel nipple for use with 2-inch NPT threaded fittings, couplings, valves, and pipe in residential and commercial plumbing and piping systems.
Installation is typically performed by a licensed plumber or pipefitter. Shut off water supply and relieve system pressure before removing or installing any threaded pipe components. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly. Follow applicable local plumbing codes and IPC guidelines for pipe support, material approval, and pressure testing requirements.
