Aqualine GCPL-300 Threaded Galvanized Coupling 3 in

Product Description

The AQUALINE GCPL-300 is a 3-inch threaded galvanized coupling designed to join two sections of threaded pipe in a secure, corrosion-resistant connection. Constructed from galvanized steel, this coupling resists rust and oxidation, making it well-suited for water distribution, irrigation, and general plumbing systems where longevity and reliability are expected. At 2.87 pounds, it carries the weight of a full-duty fitting. Licensed plumbers and pipefitters rely on this type of coupling in both new construction and repair work where standard threaded pipe connections are specified.

This coupling is appropriate for use in residential and light commercial plumbing applications involving 3-inch threaded galvanized pipe runs. Typical install scenarios include water supply lines, drainage tie-ins, and utility piping where galvanized fittings are called out by spec or code. It is sold in single-unit increments, making it a practical choice for service calls and small-quantity repairs.

Compatibility

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing any existing fittings. Apply pipe thread sealant or PTFE tape to the male threads before hand-tightening and then wrench-tightening the coupling. Avoid over-tightening, which can crack the fitting or damage the pipe threads.
