Eaton 04Z-04L-BG Jis 30 Flare Swivel Straight Fitting

Product Description

The EATON 04Z-04L-BG is a female JIS 30 flare swivel straight fitting designed for hydraulic hose assemblies. It provides a leak-resistant swivel connection between a hydraulic hose and a fixed port, allowing rotational adjustment during assembly without twisting the hose. Constructed from steel, this fitting accepts a 4 mm (1/4 inch) hose and threads into a G 1/4-19 port. The JIS 30-degree flare seating surface ensures reliable metal-to-metal sealing under hydraulic system pressures. Hydraulic technicians and fluid power specialists install this fitting in mobile and industrial hydraulic systems where a straight, female end-of-line connection is required.

This fitting is suited for use in hydraulic hose fabrication and repair across mobile equipment, industrial machinery, and other fluid power applications that require a G 1/4-19 port thread and a JIS 30-degree flare seat. The swivel design simplifies routing and installation in tight or awkward spaces where a fixed-end fitting would cause hose strain. It is sold individually and is appropriate for professional hose assembly shops and field service technicians working with JIS-standard hydraulic circuits.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before removing or installing any fitting. Use the 3/4 inch hex to tighten with an appropriate open-end or combination wrench; do not use pipe wrenches or tools that may damage the hex. Inspect the JIS 30-degree flare seating surface for nicks or debris before assembly to ensure a proper metal-to-metal seal.
