Eaton 04Z-P05-BG Hydraulic Hose O-ring Fitting 4mm

Product Description

The EATON 04Z-P05-BG is a male straight thread O-ring fitting designed for hydraulic hose assemblies. It features a 1/2-20 thread size and an inverted shaft type, making it suitable for high-pressure hydraulic lines where a leak-free seal is required. Constructed from steel, this fitting provides the durability needed in demanding fluid power applications. The O-ring face seal design minimizes the risk of leakage at connection points. This type of fitting is typically installed by hydraulic technicians and mechanical maintenance professionals working on mobile or industrial hydraulic systems.

This fitting is used in hydraulic hose assemblies on mobile equipment, industrial machinery, and fluid power systems. The inverted configuration suits specific hose end orientations where a standard straight fitting would create routing conflicts. With a 4 mm hose size and 1/2-20 thread, it is appropriate for medium-duty hydraulic circuits operating in both residential service equipment and commercial or industrial settings. Installation requires proper O-ring seating to ensure a reliable, leak-free connection under pressure.

Key Features

• Male straight thread O-ring fitting for reliable, low-leak hydraulic connections
• Steel construction for strength in high-pressure hydraulic environments
• 1/2-20 thread size for precise thread engagement
• Inverted shaft type accommodates specific hose routing requirements
• Compact dimensions support tight installation spaces

Compatibility

Designed as an OEM-style replacement fitting for hydraulic hose assemblies requiring a 4 mm, 1/2-20 male straight thread O-ring connection with an inverted shaft configuration.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and bleed the hydraulic system completely before removing or installing any fittings. Inspect the O-ring for damage before assembly and ensure it is properly seated to achieve a leak-free connection. Do not overtighten; follow standard hydraulic fitting torque practices using an appropriate wrench on the hex.
