Value Collection G291 80 Malleable Iron Square Plug 3 in

Product Description

The VALUE COLLECTION G291 80 is a malleable iron pipe square plug designed to seal the end of a threaded pipe or fitting in piping systems handling liquid, gas, or steam. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 plug provides a reliable, pressure-tested closure for 3-inch threaded pipe ends. The square head profile allows for standard wrench engagement during installation and removal. It is a common component in commercial and industrial piping assemblies installed by licensed plumbers and pipefitters.

This square plug is suited for use in residential and commercial piping systems where a threaded pipe terminus must be capped and sealed. Typical applications include shutoff points, pressure test ports, and service connections in water, gas, and low-pressure steam distribution lines. The malleable iron construction handles the mechanical stress and thermal cycling common in these environments. It is installed wherever a Class 150 threaded plug is required per system design or code specification.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the piping system completely before installing or removing any threaded plug. Apply thread sealant or PTFE tape appropriate for the service medium before threading the plug into the fitting. Do not overtighten, as malleable iron threads can be damaged by excessive torque.
