The AQUALINE GCPL-200 is a 2-inch threaded galvanized steel coupling designed for joining threaded pipe sections in water supply, irrigation, and general plumbing systems. The hot-dip galvanized finish provides corrosion resistance suited to wet and outdoor environments. Internal threads on both ends accept standard NPT pipe, allowing a secure, leak-resistant mechanical connection without soldering or special tooling. Licensed plumbers and pipefitters install this fitting in residential and light commercial applications where a reliable, code-compliant threaded joint is required.
This coupling is used in water distribution lines, irrigation mainlines, and general-purpose piping where 2-inch threaded galvanized connections are specified. It is suitable for above-grade and below-grade installations in environments that call for galvanized steel over copper or plastic alternatives. The 2-inch size is a common nominal pipe size in commercial water supply and fire protection rough-in work, as well as residential irrigation systems.
Designed as an OEM-style replacement and standard fitting for 2-inch NPT threaded galvanized steel piping systems in residential and commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the water supply before making or breaking any threaded connections. Apply thread sealant tape or pipe dope to male threads before assembly and tighten with a pipe wrench to achieve a leak-free joint. Avoid overtightening, which can crack fittings or damage threads.
