Eaton 2081-8-6S Pipe Bushing 1/2 in Male 3/8 in Female Mnpt Fnpt

Product Description

The EATON 2081-8-6S is a straight steel pipe bushing designed to reduce a 1/2 inch MNPT male thread connection down to a 3/8 inch FNPT female thread connection. Built for industrial and trade applications, this bushing handles system pressures up to 5,000 psi and operating temperatures ranging from -65 degrees F to 400 degrees F. The steel construction provides durability in demanding hydraulic, pneumatic, and plumbing installations. Plumbers, pipefitters, and industrial technicians install this fitting when adapting between mismatched pipe thread sizes in high-pressure systems.

This bushing is suited for use in hydraulic lines, compressed air systems, industrial process piping, and similar high-pressure fluid or gas applications where a threaded size reduction is required inline. The straight configuration keeps the transition compact, making it practical in tight spaces or panel-mounted assemblies. Its MNPT x FNPT connection type makes it compatible with standard NPT-threaded pipe, valves, fittings, and manifolds commonly found in commercial and industrial installations.

Key Features

• Reduces 1/2 inch male NPT to 3/8 inch female NPT in a straight configuration
• Rated to 5,000 psi maximum working pressure for high-pressure system use
• Wide operating temperature range: -65 degrees F to 400 degrees F
• Steel construction for strength and durability in industrial environments
• MNPT x FNPT connection type for compatibility with standard NPT threaded components
• Meets SAE 140140 standards

Compatibility

Designed as an OEM-style replacement or new-installation pipe bushing for standard NPT-threaded hydraulic, pneumatic, and industrial piping systems requiring a 1/2 inch male to 3/8 inch female thread reduction.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or industrial technician. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to the male threads per the system fluid compatibility requirements. Verify thread engagement and inspect for leaks before returning the system to full operating pressure.
