Matco-norca zmbpl08 2 Inch Class 150 Black Malleable Iron Plug

Product Description

The MATCO-NORCA zmbpl08 is a 2 inch square head pipe plug rated at Class 150, manufactured from Chinese malleable iron meeting ASTM A197/A197M specification. This cored, solid plug features male threaded end connections conforming to ASME B1.20.1 thread standards. It carries a black finish and is rated for temperatures up to 550 degrees F. Plumbers, pipefitters, and mechanical contractors use this fitting to cap off threaded pipe ends in fire protection, industrial, and general plumbing systems. The square head drive design allows installation and removal with a standard socket or wrench without damaging the fitting body.

This plug is suited for use in residential and commercial piping systems where a reliable, pressure-rated threaded closure is required. At 2 inches nominal pipe size and 1.56 inches overall length, it fits standard NPT threaded pipe and fittings. Applicable certifications include UL and FM listings, making it appropriate for fire protection piping installations as well as general mechanical systems requiring listed components.
