Eaton 04Z-754-BG Flareless Tube Rigid Ermeto Hydraulic Fitting

Product Description

The EATON 04Z-754-BG is a flareless tube rigid Ermeto 7000 Series hydraulic fitting designed for high-pressure hydraulic line connections in industrial and mobile equipment applications. Machined from steel and finished with an O-ring boss (ORB) port interface, this fitting accepts a 4 mm tube and threads at 7/16-20. It provides a leak-resistant, rigid tube-end connection without requiring flaring, making it a dependable choice for hydraulic systems where tube movement is not needed. Licensed hydraulic technicians and industrial maintenance professionals install this fitting as part of clean, permanent hydraulic circuit assemblies.

This fitting is suited for use in fixed hydraulic circuits on industrial machinery, mobile equipment, and hydraulic power units. Its ORB thread interface allows direct porting into manifolds, cylinders, valves, and pumps with standard SAE O-ring boss ports. The 4 mm tube size and 7/16-20 thread make it applicable in compact hydraulic line runs requiring reliable flareless bite-ring style tube retention at system pressures consistent with the Ermeto 7000 Series rating.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect the tube end for squareness and ensure the bite ring is properly seated before torquing. Follow the fitting manufacturer's assembly instructions for Ermeto-style flareless connections to achieve correct bite ring engagement without over-tightening.
