Eaton 3220X4X2 Pipe Bushing 1/4 X 1/8 Inch Mnptf Fnptf 6000 Psi

Product Description

The EATON 3220X4X2 is a straight pipe bushing designed to reduce a 1/4 inch male MNPTF thread down to a 1/8 inch female FNPTF thread. This fitting is used to connect or adapt hydraulic and fluid power lines where thread size reduction is required in-line. It is rated to a maximum working pressure of 6000 psi and handles temperatures from -65 degrees F to 250 degrees F. The straight configuration and standard NPT thread form make this a reliable choice for plumbing, hydraulic, and industrial fluid systems. Installation is handled by licensed plumbers, pipefitters, and hydraulic system technicians.

This bushing is suited for use in industrial hydraulic systems, pneumatic plumbing assemblies, and fluid transfer lines requiring a 1/4 inch to 1/8 inch MNPTF x FNPTF thread reduction. Its compact overall length of 0.5625 inches and 0.625 inch hex size allow installation in tight manifold or port configurations. It is commonly used when adapting standard pipe fittings to instrumentation ports, valve bodies, or distribution blocks in commercial and industrial settings.

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for industrial hydraulic and fluid power systems using standard MNPTF x FNPTF pipe thread connections.

Installation Notes

Installation is typically performed by licensed pipefitters, plumbers, or hydraulic technicians. De-pressurize and isolate the fluid system completely before removing or installing any fittings. Apply thread sealant appropriate for the system fluid and pressure rating. Tighten using a wrench on the hex flats only — do not apply torque to connected tubing or hose assemblies.
