The AQUALINE GCPL-250 is a 2.5-inch threaded galvanized steel coupling designed to join two sections of threaded pipe in water distribution, irrigation, and general plumbing systems. The galvanized finish provides corrosion resistance suited to wet environments and outdoor installations. This fitting accepts standard NPT threads on both ends and is installed by licensed plumbers and experienced pipefitters working on commercial or residential piping systems. At 2.21 pounds, the coupling is a heavy-duty fitting appropriate for mid-to-large diameter piping runs.
This coupling is commonly used in water supply lines, irrigation mains, fire protection piping, and industrial fluid transfer applications where a 2.5-inch threaded connection is required. It is suited for both above-ground and below-ground installations where galvanized fittings are specified. Pool and water treatment contractors also use this size for equipment pad plumbing and pump connections on larger commercial systems.
Designed as a standard replacement or new-installation fitting for 2.5-inch NPT threaded galvanized pipe systems used in plumbing, irrigation, and water distribution applications.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off and depressurize the water supply before removing any existing fittings. Apply thread sealant tape or pipe dope to all male threads before assembly. Do not overtighten, as this can crack the coupling or damage the pipe threads.
