Eaton 04E-664 Hydraulic Hose Female Swivel 90 Elbow

Product Description

The EATON 04E-664 is a female swivel 90-degree elbow hydraulic hose fitting designed for use in high-pressure hydraulic systems. Machined from steel, this SAE-series fitting accepts 1/4-inch hose and uses a 7/16-20 threaded connection. It is rated for a maximum working pressure of 7000 psi, making it suitable for demanding mobile and industrial hydraulic circuits. The swivel design allows the fitting to rotate during installation, reducing hose twist and simplifying routing in tight spaces. Hydraulic technicians and fluid power mechanics install this type of fitting when a hard 90-degree turn is required at the hose termination point.

This fitting is intended for use in hydraulic hose assemblies requiring a 90-degree change of direction at the female-swivel end. It is compatible with EATON hose series H009, H209, H243, H265, H275, H277, H285, H435, and H436. Typical applications include mobile equipment, agricultural machinery, construction equipment, and industrial hydraulic power units where compact routing and reliable high-pressure sealing are required.

Key Features

Compatibility

Designed for use with EATON hose series H009, H209, H243, H265, H275, H277, H285, H435, and H436 in 1/4-inch hose diameter assemblies.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Use the correct wrench on the 7/16-inch hex to avoid deforming the fitting body, and do not over-torque the swivel nut. Confirm that the hose series and size match the fitting specifications before final assembly, and pressure-test the system before returning it to service.
