Eaton 04Z-506-BG Male Sae 37 Jic Rigid Fitting 9/16-18

Product Description

The EATON 04Z-506-BG is a male SAE 37-degree JIC rigid hydraulic hose fitting manufactured from steel. It is designed to create a secure, leak-resistant connection in hydraulic fluid lines by forming a metal-to-metal seal at the 37-degree flare seat. This fitting accepts a 4 mm hose size with a 9/16-18 thread and uses a 5/8-inch hex for wrenching. It is a standard component in hydraulic plumbing assemblies found in industrial, mobile, and equipment maintenance applications. Installation is performed by hydraulic technicians and equipment mechanics working on fluid power systems.

This fitting is suited for rigid-connection hydraulic line assemblies where JIC 37-degree flare fittings are the specified standard. Typical applications include mobile equipment, industrial machinery, and hydraulic power units requiring a 9/16-18 threaded male JIC end. The steel construction makes it appropriate for moderate- to high-pressure hydraulic circuits where durability and dimensional consistency are required. It ships in a package quantity of one and is available as a single-unit replacement or service part.

Key Features

• SAE 37-degree JIC flare geometry provides a reliable metal-to-metal seal without the need for additional sealant
• Steel construction for strength and compatibility with standard hydraulic fluids
• 9/16-18 thread size for direct engagement with matching JIC female fittings
• 5/8-inch hex size allows use of standard open-end or combination wrenches
• Rigid fitting style eliminates hose-end articulation for fixed-line installations

Compatibility

Designed as an OEM-style replacement rigid JIC fitting for hydraulic hose assemblies requiring a male SAE 37-degree JIC end with 9/16-18 thread and 4 mm hose size.

Installation Notes

Installation should be performed by a qualified hydraulic technician or equipment mechanic. Depressurize and drain the hydraulic system fully before removing or installing any fittings. Inspect the flare seat and mating surface for nicks or debris before assembly, as contamination can prevent a proper seal. Tighten to the fitting manufacturer's recommended procedure using a backup wrench to avoid twisting the hose or mating component.
