Parker 10543-4-4 Male Rigid Hydraulic Hose Fitting

Product Description

The PARKER 10543-4-4 is a male rigid straight fitting designed for use with hydraulic hose assemblies in fluid power systems. Built from steel, this threaded SAE fitting connects to 1/4 inch (0.25 inch ID, hose size 4) hydraulic hose using a standard male SAE thread interface. The overall length is 1.64 inches. Its straight configuration makes it a direct, no-angle connection point for hydraulic lines in mobile equipment, industrial machinery, and fluid transfer applications. Installation is handled by hydraulic technicians and fluid power specialists working with medium-pressure hose assemblies.

This fitting is suited for use in hydraulic systems requiring a reliable male rigid end connection. It is compatible with a range of Parker hose series and is appropriate for both OEM assembly and field repair applications. The threaded SAE connection type is common in industrial and mobile hydraulic circuits where a secure, leak-resistant joint is required at the hose-to-port or hose-to-component interface.

Installation Notes

Hydraulic fittings of this type are installed by qualified fluid power technicians or hydraulic system mechanics. Always depressurize and bleed down the hydraulic circuit fully before disconnecting or installing any fitting. Inspect mating threads and sealing surfaces for damage before assembly, and torque to the fitting manufacturer and system design specifications. Compliance with applicable industry standards and equipment OEM guidelines should be followed during assembly.
