Eaton 2083-4-4S Hex Plug 1/4 Inch Mnpt 9500 Psi

Product Description

The EATON 2083-4-4S is a straight hex plug designed to seal off open ports in hydraulic and industrial piping systems. Threaded with a 1/4 inch MNPT male connection, this fitting handles maximum working pressures up to 9500 psi and operates across a wide temperature range of -65 degrees F to 400 degrees F. The hex-drive head allows installation with standard hand tools, making port closure fast and secure during system assembly or maintenance. Licensed plumbers, pipefitters, and hydraulic technicians working on high-pressure fluid systems rely on this type of fitting to blank off unused ports without compromising system integrity.

The 2083-4-4S is suited for industrial and hydraulic applications where a reliable MNPT-threaded port plug is required. Typical use cases include sealing unused manifold ports, capping test points, and blanking off branch connections during system reconfiguration or pressure testing. The straight fitting shape and standard MNPT thread make it broadly applicable across hydraulic power units, fluid distribution manifolds, and industrial pipe assemblies operating at elevated pressures and temperatures.

Compatibility

Designed as an OEM-style replacement hex plug for industrial and hydraulic piping systems requiring a 1/4 inch MNPT male threaded port closure rated for high-pressure service.

Installation Notes

Installation is performed by qualified pipefitters or hydraulic technicians. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply thread sealant appropriate for the system fluid and pressure rating. Do not overtighten; consult the system manufacturer's guidelines for proper assembly practice.
