Anderson Metals 756121-08 Hex Plug 1/2-14 Mnpt Brass

Product Description

The ANDERSON METALS 756121-08 is a hex plug fitting designed to close off the end of a male NPT pipe thread. It is machined from lead free brass and rated to 1000 psi working pressure. The 1/2-14 MNPT thread is the industry-standard taper thread size, making this plug a common maintenance and installation component in plumbing, gas distribution, and fluid handling systems. Plumbers, pipefitters, and HVAC technicians use this fitting to cap unused ports, isolate branch lines, or seal test points during system commissioning. Its hex body allows standard wrench engagement for reliable installation and removal.

This hex plug is suited for use in residential and commercial piping systems where a reliable MNPT cap is required. Approved applications include potable water supply lines, grease systems, fuel lines, and LP and natural gas distribution. The lead free brass construction meets requirements for contact with drinking water, making it appropriate for installation in potable water systems under applicable plumbing codes. It is a compact, single-piece fitting with no moving parts, sized for 1/2 inch nominal pipe connections.
