The AQUALINE GCPL-150 is a 1.5-inch threaded galvanized steel coupling designed for joining sections of threaded pipe in residential and light commercial plumbing systems. Galvanized construction provides corrosion resistance suitable for water supply and general-purpose piping applications. The threaded ends accept standard NPT pipe connections, making installation straightforward with common hand tools. This fitting is handled by licensed plumbers and pipefitters during new construction, renovation, and repair work on iron or galvanized pipe systems.
The GCPL-150 is well suited for water distribution lines, irrigation supply runs, and general utility piping where threaded galvanized fittings are specified. Its 1.5-inch pipe size accommodates a common mid-range flow application in both residential and light commercial settings. It ships in single-unit increments, making it easy to order exact quantities for service calls or small jobs.
Designed as an OEM-style replacement or standard fitting for 1.5-inch NPT threaded galvanized pipe systems in residential and light commercial plumbing installations.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off the water supply and depressurize the line before removing or installing any threaded fittings. Apply thread sealant tape or pipe compound to male threads before assembly, and tighten with a pipe wrench to a secure, leak-free fit. Do not over-tighten, as this can crack or distort the fitting.
