Eaton 08Z-258-BG Hydraulic Hose Fitting 1/2-14 Nptf Steel

Product Description

The EATON 08Z-258-BG is a female pipe rigid fitting designed for hydraulic hose assemblies. It accepts an 8 mm hose and features a 1/2-14 NPTF thread for a pressure-tight, dryseal connection without the need for additional sealant tape in most applications. Constructed from steel, this fitting is built to withstand the mechanical and pressure demands typical of hydraulic systems. The hex size measures 1-1/16 inches, accommodating standard hydraulic wrenches for secure installation. Hydraulic technicians and fluid-power specialists install this type of fitting when assembling or repairing high-pressure hose lines in mobile, industrial, and stationary hydraulic circuits.

This fitting is suited for use in hydraulic hose assemblies requiring a female pipe rigid end connection with NPTF dryseal threading. It is commonly installed at pump outlets, cylinder ports, valve bodies, and manifold connections where a fixed, non-swivel hose termination is appropriate. The rigid design prevents hose rotation after assembly, which is preferred in installations where hose routing is fixed and movement at the fitting end is not required. Both mobile equipment and stationary industrial machinery applications are typical for this fitting configuration.

Key Features

• Female pipe rigid fitting design — hose does not rotate after assembly
• 1/2-14 NPTF dryseal thread provides a pressure-tight connection
• Compatible with 8 mm hose size, with a 1/2-inch hose diameter
• Steel construction for durability in high-pressure hydraulic environments
• 1-1/16-inch hex size fits standard hydraulic assembly tooling

Compatibility

Designed as an OEM-style replacement fitting for hydraulic hose assemblies requiring a female pipe rigid end with 1/2-14 NPTF thread and an 8 mm hose size.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the mating port threads for damage or contamination before assembly, and verify NPTF thread engagement is correct for a dryseal connection. Follow equipment manufacturer torque guidance and applicable industry standards for hydraulic fitting assembly.
