Value Collection B-PLG12 Square Plug 1-1/4 in Malleable Iron

Product Description

The VALUE COLLECTION B-PLG12 is a malleable iron square plug designed to close off threaded pipe openings in piping systems. Finished in black and rated Class 150, this plug accepts a standard threaded connection and holds a liquid and gas pressure rating of 300 psi. It is used by plumbers and pipefitters to seal unused branch outlets, cap off test ports, or blank end connections during system servicing or installation. The square head drive allows for wrench engagement without a separate tool recess.

This square plug is suited for use in low-to-medium pressure liquid and gas piping systems in residential and light commercial applications. The threaded end connection makes it compatible with standard NPT-threaded pipe assemblies. Typical install scenarios include capping branch tees, sealing excess outlets on manifolds, and closing off test ports after pressure testing is complete.

Key Features

• Malleable iron construction for strength and thread integrity under pressure
• Black finish for corrosion resistance and identification in ferrous piping systems
• Class 150 pressure classification with a 300 psi liquid and gas pressure rating
• Threaded end connection for standard NPT pipe fitting engagement
• Square head profile allows wrench or socket drive installation

Compatibility

Designed as an OEM-style replacement or service fitting for 1-1/4 inch threaded pipe assemblies in Class 150 malleable iron piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working on threaded iron pipe systems. Depressurize and isolate the relevant section of piping before installing or removing any threaded plug. Apply appropriate thread sealant or tape in accordance with local plumbing codes and IFGC or IPC requirements before threading the plug into the fitting. Do not overtighten; use a wrench on the square head and stop when the plug is snug and leak-free.
