Eaton 04E-604 Hydraulic Hose Female Swivel Fitting Sae

Product Description

The EATON 04E-604 is a female swivel fitting designed for hydraulic hose assemblies in high-pressure fluid power systems. Built from steel, this straight, threaded fitting connects to hose with a 1/4 inch inside diameter and a 7/16-20 SAE thread. It is rated for a maximum working pressure of 7000 psi, making it suitable for demanding hydraulic circuits found in industrial, mobile, and construction equipment. The swivel design allows for rotational adjustment during assembly, reducing hose twist and stress at the connection point. Hydraulic technicians and fluid power specialists are the primary installers of this fitting.

The 04E-604 belongs to EATON Series E and is intended for use with compatible SAE hydraulic hose in 1/4 inch hose diameter applications. It is well-suited for mobile hydraulic systems, industrial machinery, and equipment requiring a reliable, leak-resistant threaded hose end. The straight configuration makes it appropriate for in-line connections where a direct hose-to-port path is needed. Compatible hose series listed by the manufacturer include H009, H209, H243, H265, H275, H277, H285, H435, and H436.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed down the hydraulic system completely before disconnecting or installing any hose end fittings. Inspect mating port threads for damage before assembly and ensure thread type compatibility to avoid cross-threading. Follow the equipment manufacturer and applicable industry standards for assembly, torque, and system testing procedures.
