Aqualine GPLUG-250 Threaded Galvanized Plug 2.5 Inches

Product Description

The AQUALINE GPLUG-250 is a 2.5-inch threaded galvanized plug designed to seal pipe ends in plumbing, HVAC, and light industrial piping systems. Constructed from galvanized steel, it resists corrosion in both wet and dry service environments. The threaded design allows for secure, wrench-tight installation into matching female-threaded fittings or pipe ends. Plumbers and pipefitters use this type of plug to cap off unused branch openings, pressure-test pipe runs, or permanently close off piping sections during system modifications.

This plug is suited for residential and light commercial plumbing installations where a 2.5-inch threaded pipe end requires a durable, corrosion-resistant seal. It is commonly installed in supply lines, drain systems, and general-purpose pipe assemblies where galvanized fittings are specified. The threaded connection is compatible with standard NPT pipe threads at this size.

Key Features

• 2.5-inch threaded connection for standard NPT pipe ends
• Galvanized steel construction for corrosion resistance in wet service conditions
• Wrench-flat hex head allows for secure, tool-driven installation and removal
• Compatible with standard galvanized pipe fitting assemblies
• Order increment of 1 for flexible single-unit purchasing

Compatibility

Designed as an OEM-style replacement or standard service fitting for 2.5-inch female NPT-threaded pipe ends in galvanized plumbing and piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the affected pipe run before threading in the plug. Apply thread sealant tape or compound to the male threads before installation to ensure a leak-free seal. Tighten with a pipe wrench to the appropriate engagement per IPC guidelines — do not overtighten, as this can crack fittings or strip threads.
