Eaton 2082-4S Hex Plug 1/4 Inch Mnpt Male Steel

Product Description

The EATON 2082-4S is a straight hex plug fitting designed to seal the end of a 1/4 inch male MNPT threaded port in hydraulic, pneumatic, and industrial piping systems. Constructed from steel, this plug is rated for a maximum working pressure of 9500 psi and a temperature range of -40 degrees F to 250 degrees F. The hex head allows for standard wrench installation, providing a secure, leak-free closure on open pipe ports. It meets SAE standards and is a common component in high-pressure fluid power and instrumentation applications. Plumbers, pipefitters, and hydraulic technicians install this fitting as part of routine system assembly or maintenance.

This hex plug is suited for sealing unused ports in hydraulic manifolds, pneumatic distribution blocks, and industrial process piping where MNPT-threaded connections are present. Its straight fitting shape makes it a direct thread-in solution for any 1/4 inch MNPT female port. Typical installations include high-pressure hydraulic systems, compressed air lines, and industrial fluid handling equipment in both commercial and light industrial settings.

Key Features

• Meets SAE standards for industrial and fluid power applications

Compatibility

Designed as an OEM-style replacement or new-installation hex plug for any system with an open 1/4 inch MNPT female threaded port in hydraulic, pneumatic, or industrial piping applications.

Installation Notes

Installation is typically performed by licensed pipefitters, hydraulic technicians, or plumbers. Depressurize and isolate the system completely before installing or removing any threaded fittings. Apply thread sealant or PTFE tape appropriate for the system fluid and pressure rating before threading the plug into the port. Follow applicable IFGC, IPC, or system manufacturer guidelines for torque and sealant selection.
