Anderson Metals 756115-08 Hollow Hex Plug 1/2-14 Mnpt

Product Description

The ANDERSON METALS 756115-08 is a hollow hex plug fitting designed for sealing threaded pipe openings in pressurized systems. Machined from lead free brass, it accepts a 1/2-14 male MNPT connection and carries a maximum working pressure rating of 1000 psi. The hollow hex design allows for a standard hex wrench or socket to engage the plug head for proper torque during installation. This fitting is compliant with lead free requirements, making it suitable for potable water service in addition to fuel and gas applications. Plumbers, pipefitters, and HVAC technicians install this type of plug during system assembly, maintenance, and pressure testing.

The 756115-08 is rated for use with potable water, grease, fuels, LP gas, and natural gas. It is well suited for residential and light commercial plumbing, gas distribution lines, and fuel system piping where a reliable threaded pipe closure is needed. The 1/2-14 MNPT thread size is one of the most common pipe thread sizes in trade work, making this plug a frequent fit in general plumbing and mechanical service scenarios.
