Eaton 3152X12 Hex Plug 3/4 in Mnptf 1200 Psi

Product Description

The EATON 3152X12 is a straight hex plug fitting designed to close off the end of a pipe or port in industrial and mechanical fluid systems. Threaded to a 3/4 inch male MNPTF connection standard, it holds a maximum working pressure of 1,200 psi and handles temperatures ranging from -65 degrees F to 250 degrees F. Its 1-1/16 inch hex drive and 7/8 inch overall length make it a compact, no-nonsense dead-end fitting. Licensed plumbers, pipefitters, and industrial maintenance technicians use this plug to cap live or test ports, isolate system sections, or seal unused outlets during service or installation work.

This fitting is suited for use in hydraulic, pneumatic, and general-purpose industrial piping systems where an MNPTF threaded closure is required. It is appropriate for both light industrial and heavy-duty service applications operating within its rated pressure and temperature envelope. The straight configuration allows direct thread-in installation without offset, making it practical for tight manifold and valve body applications common in commercial HVAC, fluid power, and plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Depressurize and isolate the system completely before removing any existing fitting or installing this plug. Apply thread sealant appropriate for the service fluid and rated for the system pressure before threading in. Tighten with a properly sized wrench on the hex flats — do not use pipe wrenches on the body.
