Multiquip 21104 Hose Assembly 5/8 ID x 54.50 45 One End

The Multiquip 21104 Hose Assembly 5/8 ID x 54.50 45 One End is a genuine OEM hose assembly designed for the STX55J6 and STX55Y6 Whiteman ride-on power trowels. As a factory-sourced component, this assembly matches the original routing, inside diameter, and end configuration used during production, ensuring it seats correctly within the hydraulic or fluid circuit it serves. Confirm your model code against STX55J6 or STX55Y6 before ordering to ensure a direct application match. DHS Equipment supplies this Multiquip 21104 as an authorized OEM replacement, so you can be confident you are receiving the correct part for your machine.

Key Features

• OEM-Spec Inner Diameter: — 5/8 in. internal diameter matches the original flow capacity and pressure rating of the circuit, preventing restriction or leakage at connection points.
• Pre-Formed 45-Degree End: — The single 45-degree angled end is factory-formed to the correct bend, allowing the hose to route and connect to the port fitting without stress on the line.
• Verified Length at 54.50 Inches: — The fixed 54.50 in. overall length matches the original run exactly, eliminating any slack or tension that could cause premature wear or fitting separation.
• Direct Fitment for STX55 Series: — Engineered specifically for STX55J6 and STX55Y6 Whiteman ride-on hydrostatic trowels, this assembly drops into the same mounting and port position as the part it replaces.
• Fluid Circuit Integrity: — A correctly sized and properly routed hose assembly maintains consistent fluid delivery across the trowel's hydraulic system, supporting steady blade control and drive response during finishing operations.

A hose assembly carries pressurized fluid between components in the machine's hydraulic system, acting as a flexible conduit that allows movement and vibration between connected parts without cracking or leaking. On a ride-on trowel like the STX55 series, the hydraulic circuit controls both blade pitch and machine drive, so a hose that is the wrong length, bore size, or end configuration can disrupt fluid flow or cause fitting leaks that degrade trowel responsiveness. When a hose assembly cracks, collapses internally, or develops a weeping fitting connection, the affected circuit loses pressure and performance drops — replacing it with the correct OEM assembly restores the system to its intended operating condition.
