Eaton 04Z-S64-BG Female Ors Swivel Fitting 4mm 9/16-18

Product Description

The EATON 04Z-S64-BG is a female ORS swivel fitting designed for hydraulic hose assemblies. It provides a leak-resistant O-ring face seal connection on the port end while the swivel design allows the hose to be positioned without twisting during installation. Built from steel, this fitting suits high-pressure hydraulic systems found in industrial, agricultural, and mobile equipment applications. It accepts a 4 mm hose with a 9/16 inch hose diameter and uses a 9/16-18 thread size. The FOR-SEAL shaft type ensures a secure face seal interface at the mating port.

This fitting is used in hydraulic plumbing applications where an ORS (O-Ring Seal) port connection is required. It is appropriate for both new hose assembly builds and replacement repairs on hydraulic systems requiring a 9/16-18 female swivel end. Typical install scenarios include mobile hydraulic equipment, skid-steer loaders, tractors, construction machinery, and industrial power units where swivel fittings reduce strain and allow flexible hose routing.

Installation Notes

Installation is typically performed by a hydraulic technician or journeyman mechanic. Always depressurize and bleed down the hydraulic system completely before disconnecting or installing any hose fitting. Inspect the O-ring for damage before assembly and replace it if worn or deformed to ensure a proper face seal. Torque to the fitting manufacturer and equipment OEM specifications using a calibrated torque wrench and a backup wrench on the mating port.
