The AQUALINE GPLUG-150 is a 1.5-inch threaded galvanized plug used to cap or seal threaded pipe openings in plumbing, HVAC, and related mechanical systems. Galvanized steel construction provides corrosion resistance in standard service conditions. The threaded design allows for a secure, leak-resistant fit when installed into a matching female-threaded fitting. This plug is a routine component used by licensed plumbers and pipefitters during system installation, maintenance, and pressure testing.
The GPLUG-150 is suited for residential and light commercial plumbing applications where a 1.5-inch threaded pipe end requires a durable, reliable closure. Typical uses include capping unused branch outlets, sealing test ports, and closing off pipe runs during phased construction or system modification. Its galvanized finish makes it appropriate for above-ground and dry interior installations.
Designed as an OEM-style replacement and standard-service plug for 1.5-inch female-threaded pipe fittings in residential and commercial plumbing and mechanical systems.
Installation is performed by a licensed plumber or qualified pipefitter. Shut off system pressure and drain the line before removing or installing any threaded plug. Apply thread sealant tape or compound to the male threads before hand-tightening, then wrench-tighten to a snug fit without over-stressing the fitting. Follow applicable IPC and local plumbing code requirements for material compatibility and pressure ratings.
