Eaton 04E-104 Male Pipe Rigid Hydraulic Hose Fitting

Product Description

The EATON 04E-104 is a male pipe rigid hydraulic hose fitting designed for high-pressure fluid conveyance in hydraulic systems. Constructed from steel with a straight shape and threaded NPT connection, this fitting accepts a 1/4-inch hose (0.25 inches inside diameter, 0.25 inches outside diameter) and is rated for a maximum working pressure of 9,500 psi. The 1/4-18 NPT thread size and 9/16-inch hex allow for secure, leak-resistant assembly using standard hand and wrench tools. This fitting is a rigid, non-swivel design intended for fixed-line hydraulic plumbing in mobile or industrial equipment. Installation and service are typically performed by hydraulic system technicians or fluid power specialists.

This fitting is suited for use in hydraulic hose assemblies across industrial, agricultural, and mobile equipment applications. Its straight configuration makes it appropriate for inline connections where hose routing allows a direct, no-angle transition from hose to port. The NPT thread standard is common in North American hydraulic systems, and the steel construction handles demanding duty cycles. Compatible hose series specified by the manufacturer include H009, H209, H243, H265, H275, H277, H285, H435, and H436, making this fitting a direct-use component within those EATON hose families.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before disconnecting or assembling any fittings. Apply thread sealant appropriate for NPT connections and torque to the fitting manufacturer or system OEM specification. Inspect threads and sealing surfaces for damage before assembly to prevent leaks under pressure.
