Product Description

The MATCO-NORCA mn-ftsp03 is a 1/2-inch forged steel square head plug designed to seal pipe openings in plumbing and piping systems. Built to ANSI/ASME B16.14 pressure rating standards, this plug is 100% pressure tested at the factory, giving installers confidence in leak-free performance. The square head drive profile allows for positive wrench engagement during installation and removal. This fitting is lead free and carries UL/FM certification, making it suitable for fire protection and industrial piping applications where listed fittings are required. Plumbers and pipefitters are the primary installers of this type of component.

This plug is appropriate for use in residential, commercial, and light industrial piping systems. It is suited for applications requiring a threaded pipe closure, including water supply lines, gas distribution piping, and fire protection systems. The UL/FM certification broadens its use in systems where listed components are mandated by the authority having jurisdiction. The fitting conforms to ANSI/ASME B16.3 and B16.14 standards, covering pressure-rated malleable iron and forged steel pipe plugs across the 1/8-inch to 6-inch diameter range.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the IPC or IFGC. Shut off the water or gas supply and depressurize the system completely before installing or removing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not overtighten, as this can crack fittings or damage threads.
