Eaton 04Z-L66-BG Female Ors Swivel 45 Elbow Fitting

Product Description

The EATON 04Z-L66-BG is a female ORS swivel 45-degree elbow hydraulic hose fitting designed for use in medium- and high-pressure hydraulic systems. Built from steel with a FOR-SEAL shaft type, this fitting accepts a 4 mm hose size and uses an 11/16-16 thread. The 45-degree elbow geometry allows technicians to route hose runs in tight spaces while maintaining a secure, leak-resistant connection at the port face. The swivel design lets the fitting body rotate during installation, reducing the chance of hose twist and simplifying assembly in confined equipment compartments. This type of fitting is typically installed by hydraulic system technicians and fluid power specialists on mobile and industrial equipment.

This fitting is suited for hydraulic plumbing applications where an ORS (O-Ring Seal) face seal connection is specified. The 45-degree elbow orientation is commonly used where straight fittings would create excessive bend radius or interference with adjacent components. The 11/16-16 thread size is a standard SAE straight thread, making this fitting compatible with ORS port configurations found on cylinders, manifolds, valves, and pumps in agricultural, construction, and industrial machinery.

Key Features

• Female ORS swivel design provides a leak-resistant face-seal connection at the port
• 45-degree elbow angle simplifies hose routing in tight or congested equipment areas
• Steel construction for durability in hydraulic pressure service
• FOR-SEAL shaft type supports proper O-ring face seal engagement
• Swivel body reduces hose twist during assembly and torque-up
• 11/16-16 SAE straight thread fits standard ORS port configurations

Compatibility

Designed as an OEM-style replacement hydraulic hose fitting for systems using SAE ORS (O-Ring Seal) female swivel connections with an 11/16-16 thread and a 4 mm hose size.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Inspect the O-ring and seating surface for damage before assembly, and replace the O-ring if any wear or deformation is present. Tighten to the fitting manufacturer's torque specifications for the thread size and material to avoid under-sealing or thread damage.
