Value Collection -12148-7 Square Plug 1-1/2 in Npt Class 3000

Product Description

The VALUE COLLECTION -12148-7 is a forged carbon steel square plug designed to seal threaded pipe openings in high-pressure piping systems. Rated at 3000 psi and manufactured to Class 3000 standards, this plug provides a reliable, leak-resistant closure in both liquid and gas service. The black finish is standard for carbon steel fittings of this type. At 1-1/2 inches NPT, it fits common pipe sizes found in commercial and industrial plumbing, process piping, and gas distribution systems. Sold in a package of two, this part is installed by licensed plumbers and pipefitters working on pressurized systems.

This square plug is suited for residential, commercial, and light industrial piping applications where a threaded dead-end closure is required. It is used to cap off unused branch outlets, test ports, or temporary openings in NPT-threaded pipe and fittings. The Class 3000 pressure rating makes it appropriate for steam, water, air, and gas service lines where elevated system pressures are present.

Installation Notes

Installation is performed by licensed plumbers or pipefitters. Depressurize and isolate the pipe section before installing or removing any threaded plug. Apply appropriate thread sealant or PTFE tape to the NPT threads before installation. Torque should be applied with a properly sized pipe wrench; do not overtighten, as this can crack fittings or damage threads. Verify system pressure rating compliance before returning the line to service.
