Eaton 3325X6X4 Hex Plug 3/8 X 1/4 Mnptf 1200 Psi

Product Description

The EATON 3325X6X4 is a male threaded hex plug fitting designed to seal and cap hydraulic and industrial pipe lines. The plug features a 3/8 x 1/4 inch male MNPTF thread configuration and is rated for a maximum working pressure of 1,200 psi. The hex body allows for standard wrench installation, providing a secure mechanical closure in pressurized fluid systems. This fitting is commonly installed by hydraulic technicians, plumbers, and industrial maintenance professionals working on fluid power, pneumatic, or process piping systems.

The 3325X6X4 is suited for use in industrial and commercial pipe assemblies where a reliable threaded plug is required to terminate or cap a line. Its operating temperature range of -65 degrees F to 250 degrees F makes it appropriate for a wide range of process environments. Typical applications include hydraulic power units, air compressor systems, and industrial fluid distribution manifolds where branch ports or test ports need to be closed off.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber. Depressurize and isolate the system before removing or installing any pipe plug. Apply appropriate thread sealant compatible with the system fluid and verify the MNPTF taper thread engagement before torquing to avoid cross-threading. Follow applicable industry and facility standards for pressure piping when returning the system to service.
