Eaton 04Z-202-BG Hydraulic Hose Female Pipe Rigid Fitting

Product Description

The EATON 04Z-202-BG is a female pipe rigid fitting designed for hydraulic hose assemblies. It provides a fixed, non-swiveling connection between a hydraulic hose and a threaded port. The fitting features a 1/8-27 NPTF thread, which creates a pressure-tight seal through thread interference rather than relying solely on a separate sealing element. Constructed from steel, it is suited for high-pressure hydraulic lines in industrial and mobile equipment applications. Hydraulic system technicians and mechanics install this type of fitting when assembling or repairing fluid power circuits that require a rigid, leak-free female pipe end connection.

This fitting is used in hydraulic hose assemblies where a 4 mm hose size and 1/8-27 NPTF female pipe thread are specified. It is appropriate for both light industrial and mobile hydraulic systems, including presses, lifts, cylinders, and similar fluid power equipment. The rigid design holds the hose end in a fixed orientation, which is important in applications where hose routing and alignment must remain consistent under pressure and vibration.

Key Features

• 1/8-27 NPTF female pipe thread provides a dry-seal, pressure-tight connection
• Rigid fitting design maintains fixed hose orientation and alignment
• Steel construction for durability in hydraulic pressure environments
• Compact hex size of 9/16 inch fits standard hydraulic fitting wrenches
• Compatible with 4 mm hose size for small-bore hydraulic line assemblies

Compatibility

Designed as an OEM-style replacement rigid fitting for hydraulic hose assemblies using a 4 mm hose size and 1/8-27 NPTF female pipe thread connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic. Depressurize and bleed the hydraulic system completely before removing or installing any fittings. Use a calibrated torque wrench and follow the equipment manufacturer's torque specifications for NPTF fittings of this thread size. Inspect the mating port threads for damage or contamination before assembly to ensure a proper dry seal.
