The AQUALINE GCPL-125 is a 1.25-inch threaded galvanized coupling designed to join two sections of threaded pipe in plumbing, irrigation, and light industrial piping systems. The galvanized steel construction provides corrosion resistance in wet and exposed environments, making it a reliable choice for water supply and drainage applications. At 0.66 pounds, it is a compact, durable fitting suited for standard pipe runs where a secure, leak-resistant threaded connection is required. Licensed plumbers and pipefitters install this coupling as a straightforward, code-compliant solution in both new construction and repair work.
This coupling is appropriate for residential and light commercial plumbing systems, irrigation lines, and general water distribution piping where 1.25-inch threaded pipe connections are specified. It is commonly used in applications requiring galvanized fittings due to moisture exposure or local code requirements. The threaded design allows for tool-based installation without welding or soldering, making it practical for field repairs and system modifications.
Designed as an OEM-style replacement and standard fitting for 1.25-inch threaded galvanized pipe systems in residential and light commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before removing any existing fittings or making new connections. Apply thread sealant tape or pipe dope to the male threads before assembly and tighten with a pipe wrench to achieve a leak-free joint. Inspect the connection for leaks after restoring system pressure.
