1/2 MPT Hex Pipe Plug

The FRAGOLA 1/2 MPT Hex Pipe Plug is a precision-engineered aluminum fitting designed specifically for sealing unused ports in various systems, including fuel systems, cooling loops, and custom hydraulic builds. This component is essential for mechanics working on fuel system modifications and engine conversions, ensuring system integrity during reconfigurations.

Constructed from lightweight aluminum, the FRAGOLA plug features a 1/2 inch male pipe thread (MPT) connection that fits directly into 1/2 MPT female ports without the need for adapters. The hex head design allows for proper torque application using a standard wrench, which is critical for sealing pressurized circuits and preventing leaks.

Anyone fabricating custom fuel rails, converting carbureted engines to fuel injection, or integrating aftermarket cooling systems will find this plug beneficial. It is particularly useful for drag racers, street rodders, and enthusiasts who frequently encounter ported manifolds and need reliable closure for dead-end ports.
