Eaton 3325X6 Hex Plug 1200 Psi 3/8 in Mnptf

Product Description

The EATON 3325X6 is an industrial pipe hex plug designed to seal threaded pipe ports in fluid and pneumatic systems. The 3/8-inch MNPTF male thread provides a tapered, pressure-tight connection without requiring additional sealing compound on properly mated female ports. Rated to 1,200 psi maximum working pressure and suitable for temperatures ranging from -65 degrees F to 250 degrees F, this plug handles demanding service conditions in hydraulic, pneumatic, and general fluid-handling applications. Licensed plumbers, pipefitters, and fluid-power technicians install this fitting during system construction, maintenance shutdowns, and pressure-testing procedures.

The 3325X6 is suited for use in industrial piping systems, hydraulic manifolds, and pneumatic assemblies where an unused port must be securely capped. Its hex drive design accepts a standard wrench for controlled installation torque without requiring specialty tools. It is appropriate for both shop fabrication and field service work across a broad range of industrial and mechanical applications.

Compatibility

Designed as an OEM-style replacement hex plug for industrial piping and hydraulic or pneumatic systems using 3/8-inch MNPTF threaded ports rated to 1,200 psi.

Installation Notes

Installation is performed by licensed pipefitters, plumbers, or fluid-power technicians. Depressurize and isolate the system completely before removing or installing any threaded pipe plugs. Use a calibrated torque wrench and follow applicable IFGC, IPC, or system manufacturer torque guidelines for tapered NPT fittings. Inspect threads for damage before installation and verify the port thread standard matches MNPTF before seating the plug.
