Anderson Metals 756109-06 Square Head Pipe Plug 3/8-18 Mnpt

Product Description

The ANDERSON METALS 756109-06 is a square head pipe plug with a 3/8-18 male NPT thread used to seal or cap pipe ends and fittings in pressurized piping systems. Rated to 1,000 psi working pressure, it is suitable for use in potable water, grease, fuel, LP gas, and natural gas applications. The square head drive profile allows installation with a standard wrench or socket without requiring a recessed driver. Lead-free construction meets the requirements for potable water service. Plumbers, pipefitters, and gas technicians install this type of plug during system assembly, pressure testing, and line capping tasks.

This plug is designed for industrial and commercial pipe systems where a reliable, high-pressure threaded closure is needed. Typical applications include capping unused ports on manifolds, valves, and tee fittings in water supply, fuel distribution, and gas piping systems. The MNPT thread standard ensures compatibility with standard NPT female-threaded fittings and components found throughout residential and commercial plumbing and gas installations.

Installation Notes

Installation is performed by licensed plumbers or gas technicians depending on the service application. Shut off and depressurize the line before installing or removing any pipe plug.
