Eaton 2081-6-4S Pipe Bushing 3/8x1/4 Mnpt Fnpt 5000 Psi

Product Description

The EATON 2081-6-4S is a straight steel pipe bushing designed to reduce a 3/8 inch male NPT thread down to a 1/4 inch female NPT thread in hydraulic, pneumatic, and industrial piping systems. Rated to 5,000 psi maximum working pressure, this bushing handles demanding service conditions across a wide temperature range of -65 degrees F to 400 degrees F. The MNPT x FNPT connection type allows direct installation into threaded ports and fittings without additional adapters. Licensed plumbers, pipefitters, and industrial maintenance technicians install this fitting as part of hydraulic manifold assemblies, compressed air lines, and fluid power systems.

This bushing is suited for industrial and commercial applications where a thread size reduction is needed in a straight-line configuration. Common install scenarios include hydraulic power units, pneumatic control panels, lube systems, and process piping where 3/8 inch ported equipment must accept 1/4 inch threaded lines or instrumentation. The steel construction and 5,000 psi pressure rating make it appropriate for high-pressure fluid power work. It meets SAE 140140 standards, confirming its fit for rated service conditions.

Compatibility

Designed as an OEM-style replacement fitting for industrial and hydraulic piping systems requiring a straight MNPT x FNPT thread reducer from 3/8 inch to 1/4 inch.

Installation Notes

Installation should be performed by a licensed pipefitter or qualified industrial maintenance technician. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply thread sealant or PTFE tape appropriate for the service fluid and pressure rating. Do not overtighten; follow applicable IFGC or system manufacturer torque guidelines for NPT steel fittings.
