Anderson Metals Corp 756109-04 Brass Square Head Pipe Plug

Product Description

The ANDERSON METALS CORP 756109-04 is a 1/4 inch male pipe thread (MPT) brass square head pipe plug designed to seal threaded pipe openings in plumbing, HVAC, and fluid handling systems. The square head profile allows for wrench engagement during installation and removal. Constructed from lead free brass, this plug meets the requirements of Public Law 111-380, making it suitable for use in potable water systems where lead free compliance is mandated. Plumbers, pipefitters, and HVAC technicians use these plugs to cap unused ports, pressure test systems, or permanently seal branch connections.

This plug is suited for residential and light commercial applications including water supply lines, gas distribution piping (where code permits brass fittings), hydronic heating systems, and compressed air lines. The 1/4 inch MPT thread size is common in fixture supply connections, manifold ports, and equipment service ports. Sold in bulk packs of 10, this SKU is a practical stocking item for service vans and shop inventory.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off system pressure and depressurize the line before installing or removing any pipe plug. Apply appropriate thread sealant or PTFE tape to the male threads before installation in accordance with local plumbing codes and IFGC or IPC requirements. Do not overtighten brass fittings in cast or soft-metal threaded ports, as brass threads can strip or crack the mating fitting.
