Aqualine GPLUG-125 Threaded Galvanized Plug 1.25 in

Product Description

The AQUALINE GPLUG-125 is a 1.25-inch threaded galvanized plug used to cap or seal threaded pipe ends in plumbing, HVAC, and industrial piping systems. The galvanized steel construction provides corrosion resistance in wet or humid environments. At 0.4 pounds, it is a compact, durable fitting suited for both new installations and maintenance work. Licensed plumbers and pipefitters install this type of plug to close off unused pipe outlets, pressure-test piping systems, or permanently seal branch lines during service or retrofit work.

This plug is designed for use in threaded pipe systems where a 1.25-inch male NPT fitting is required to close a female-threaded port. Common applications include residential and light commercial plumbing rough-in, hydronic heating systems, and general pipe work where a secure, leak-resistant seal on an open pipe end is needed. The galvanized finish makes it suitable for above-ground and dry interior installations.

Key Features

• Galvanized steel construction resists corrosion in typical plumbing environments

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and depressurize the system before threading the plug into the fitting. Apply thread sealant tape or pipe dope to the male threads before installation to ensure a leak-free seal. Follow applicable IPC or local plumbing code requirements for pressure testing and fitting specifications.
