Eaton 04Z-755-BG Hydraulic Fitting 4mm 1/2-20 Steel Inverted

Product Description

The EATON 04Z-755-BG is a flareless tube rigid Ermeto 7000 Series hydraulic fitting designed for use in high-pressure hydraulic plumbing systems. Machined from steel, this inverted-style fitting provides a secure, leak-resistant connection without requiring tube flaring. It accepts a 4 mm hose size with a 1/2-20 thread and measures 1.58 inches in length with a 0.88-inch height and 0.88-inch width. At 0.11 pounds, it is a compact, precision component used by hydraulic technicians and industrial maintenance professionals to terminate or connect tube lines in demanding fluid power applications.

This fitting is suited for rigid tube terminations in hydraulic systems where flareless Ermeto-style connections are specified. Typical installations include mobile equipment hydraulics, industrial machinery, and fluid power circuits requiring the 7000 Series Ermeto standard. It is appropriate for applications calling for a 4 mm tube OD connection with a 1/2-20 UNF inverted thread interface. Hydraulic system builders and maintenance technicians working on medium- to high-pressure circuits will encounter this fitting in both OEM assembly and field repair contexts.

Key Features

• Flareless Ermeto 7000 Series design eliminates the need for tube flaring during assembly
• Inverted shaft type provides a secure, orientation-specific connection for rigid tube runs
• Steel construction offers durability in high-pressure hydraulic environments
• 4 mm hose size with 1/2-20 thread for precise fitment in specified hydraulic circuits
• Compact footprint: 1.58 inches long, 0.88 inches wide, 0.88 inches tall

Compatibility

Designed as an OEM-style replacement fitting for hydraulic systems specifying Ermeto 7000 Series flareless tube rigid connections with a 4 mm tube size and 1/2-20 thread.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and lock out the hydraulic system completely before removing or installing any fitting. Follow the equipment manufacturer's torque and assembly procedures for Ermeto-style flareless fittings; correct bite-ring pre-swaging is critical to achieving a leak-free joint. Inspect threads and seating surfaces for damage before assembly and verify tube OD dimensions match the fitting specification.
