Eaton 04Z-P06-BG Hydraulic Hose O-ring Fitting 9/16-18

Product Description

The EATON 04Z-P06-BG is a male straight thread O-ring fitting designed for hydraulic hose assemblies. It provides a leak-resistant sealed connection using an O-ring at the thread interface, which reduces the risk of fluid bypass under pressure. Constructed from steel, this fitting handles the mechanical demands of hydraulic systems in industrial, mobile, and construction equipment applications. The 9/16-18 thread size and MPT shaft type make it a direct, low-prep installation component for technicians building or repairing hydraulic lines. The 11/16-inch hex allows standard wrench engagement during torquing.

This fitting is suited for hydraulic hose assemblies requiring a reliable straight-thread O-ring seal at the port connection. It is commonly installed in mobile hydraulic circuits, agricultural equipment, construction machinery, and industrial power units where a 4 mm hose size and 9/16-18 straight thread port are specified. The MPT shaft type is compatible with standard hydraulic hose crimping and fitting assemblies used by fluid power technicians and hydraulic shop professionals.

Compatibility

Designed as an OEM-style replacement fitting for hydraulic hose assemblies specifying a 4 mm hose size with a 9/16-18 straight thread O-ring port connection.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic systems professional. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect the O-ring seat and O-ring for damage before assembly, and ensure the O-ring is properly seated to achieve a reliable seal. Use a calibrated torque wrench on the 11/16-inch hex to avoid over-torquing, which can damage the O-ring or thread.
