Eaton 08Z-058-BG Hydraulic Hose Swivel Fitting 8mm 1/2-14 Npsm

Product Description

The EATON 08Z-058-BG is a female straight pipe swivel fitting designed for hydraulic hose assemblies requiring a reliable, leak-resistant connection. Machined from steel, this fitting accepts an 8 mm hose with a 1/2-inch outside diameter and uses a 1/2-14 NPSM thread form, which is a straight mechanical pipe thread that engages without tapering. The swivel design allows the hose end to rotate during installation, reducing assembly torque and preventing hose twist. Hydraulic technicians and fluid-power specialists use this fitting when terminating or repairing medium-pressure hose lines in mobile and industrial hydraulic systems.

This fitting is suited for straight-entry connections on hydraulic circuits found in agricultural equipment, construction machinery, and industrial power units. The female swivel end mates to a male NPSM port on pumps, valves, cylinders, or manifold blocks. Its compact envelope, measuring 2.28 inches in length and 1.22 inches across, fits in space-constrained plumbing layouts. One fitting is included per package. Installation is performed by qualified hydraulic technicians or fluid-power mechanics familiar with hose routing and fitting assembly procedures.

Key Features

• Steel construction for durability in hydraulic service environments
• 1/2-14 NPSM straight pipe thread for mechanical engagement without taper interference
• Swivel body allows hose rotation during assembly to eliminate twist
• Accepts 8 mm hose with a 1/2-inch hose diameter
• Compact form factor at 2.28 inches length for tight installations

Compatibility

Designed as an OEM-style replacement swivel fitting for hydraulic hose assemblies using 8 mm hose and 1/2-14 NPSM female straight pipe thread connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and bleed the hydraulic system fully before disconnecting any fittings or hose assemblies. Inspect the mating port threads for damage before assembly, and apply a compatible thread sealant or O-ring as required by the port design. Do not over-torque the swivel nut, as NPSM is a straight thread and relies on a sealing surface rather than thread interference.
