Eaton 04Z-504-BG Male Sae 37 Jic Rigid Hose Fitting

Product Description

The EATON 04Z-504-BG is a male SAE 37-degree JIC rigid hydraulic hose fitting manufactured from steel. It connects hydraulic hose assemblies to mating JIC female swivel or rigid ports, providing a leak-resistant 37-degree flare seat. The 7/16-20 UNF thread and 4 mm hose size make it suitable for compact hydraulic circuits in mobile equipment, industrial machinery, and fluid power systems. At 0.13 pounds, it is a lightweight but durable single-piece hardware component. Installation is handled by hydraulic system technicians and fluid power mechanics performing hose assembly fabrication or field repairs.

This fitting is used in hydraulic systems requiring a rigid, non-rotating male JIC connection at the hose end. Typical applications include mobile hydraulic equipment, agricultural machinery, construction equipment, and industrial fluid power circuits where SAE J514 JIC 37-degree flare connections are specified. The steel construction handles the pressure demands of standard hydraulic service lines.

Key Features

• SAE 37-degree JIC flare seat provides a reliable metal-to-metal seal
• Rigid fitting design — no swivel rotation, suited for fixed-position hose routing
• Steel construction for durability in hydraulic service environments
• 7/16-20 UNF thread for standard JIC port compatibility
• Compact dimensions allow use in tight hydraulic plumbing layouts

Compatibility

Designed as an OEM-style replacement male SAE 37-degree JIC rigid hose fitting for hydraulic hose assemblies requiring a 4 mm hose size and 7/16-20 UNF thread connection.

Installation Notes

Hydraulic system technicians and fluid power mechanics should depressurize and bleed the hydraulic circuit fully before removing or installing this fitting. Inspect the mating JIC female port flare seat for damage before assembly. Tighten to the torque value specified by the equipment manufacturer for 7/16-20 JIC connections — do not over-torque, as this can deform the flare seat. Follow applicable fluid power standards and equipment service documentation during installation.
