Eaton 3220X12X8 Pipe Bushing 3/4 X 1/2 in Mnptf X Fnptf

Product Description

The EATON 3220X12X8 is a straight industrial pipe bushing designed to reduce a 3/4-inch male NPT fitting to a 1/2-inch female NPT port. Built for high-pressure hydraulic and pneumatic plumbing applications, it connects MNPTF to FNPTF threads in a compact straight configuration. The bushing is rated to 4,000 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F. At 0.12 pounds and 7/8 inches overall length, it fits in tight plumbing assemblies where a reducer is needed without adding significant bulk. Licensed plumbers, pipefitters, and hydraulic system technicians are the primary installers of this fitting type.

This bushing is used in industrial, commercial, and heavy-duty fluid power systems where a larger-threaded supply line or manifold port must transition down to a smaller-threaded component. Typical applications include hydraulic power units, compressed air distribution systems, and fluid transfer lines operating under sustained high pressure. The MNPTF x FNPTF thread configuration makes it well suited for use in steel pipe assemblies conforming to ASA, ASME, and SAE standards.

Key Features

• Maximum working pressure of 4,000 psi for demanding hydraulic and pneumatic service
• Wide temperature range: -65 degrees F to 250 degrees F
• Straight bushing profile with 3/4-inch male thread and 1/2-inch female thread
• MNPTF x FNPTF connection type for standard tapered NPT assemblies
• 1-1/8-inch hex size for wrench engagement during installation
• Compliant with ASA, ASME, and SAE standards

Compatibility

Designed as an OEM-style replacement bushing for industrial pipe assemblies requiring a 3/4-inch MNPTF to 1/2-inch FNPTF straight reducer fitting.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or hydraulic technician. Depressurize and isolate the system completely before removing or installing any threaded fittings. Use a calibrated torque wrench sized for the 1-1/8-inch hex and apply thread sealant appropriate for the fluid service and pressure rating. Follow applicable ASME and SAE standards for threaded pipe joint assembly.
