Multiquip 21356 Hose Assembly 5/8 ID x 74 Straight Ends

The Multiquip 21356 is a genuine OEM Hose Assembly 5/8 ID x 74 Straight Ends designed for the STX55J6 and STX55Y6 super-sized hydrostatic ride-on power trowels. As a direct OEM replacement, this hose assembly is manufactured to the exact specifications required for correct hydraulic routing and connection on these machines. Sourced directly through authorized Multiquip distribution, part 21356 ensures you are installing the correct component with no uncertainty about fitment. DHS Equipment stocks this part to keep your trowel operating at full capacity.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact dimensional and pressure tolerances, ensuring the hose walls, fittings, and end connections hold up under the hydraulic demands of a ride-on trowel.
• Straight-End Connections — The straight-end configuration on both ends allows direct port-to-port installation, simplifying routing and reconnection during service.
• Confirmed STX55 Series Fitment — Verified for the STX55J6 and STX55Y6 hydrostatic ride-on trowels; cross-reference part number 21356 against your machine's parts diagram before ordering.
• Maintains Hydraulic System Integrity — A correctly seated hose assembly preserves proper hydraulic pressure and flow throughout the trowel's blade pitch and drive circuits, keeping blade response consistent and predictable.
• Leak Prevention — A worn or cracked hose risks hydraulic fluid loss that can cause erratic blade control or loss of drive function; replacing with this OEM assembly restores a sealed, reliable hydraulic circuit.

A hydraulic hose assembly on a hydrostatic ride-on trowel carries pressurized fluid between the engine-driven hydraulic pump and the control circuits that manage blade pitch and machine movement. The 5/8-inch inner diameter and 74-inch overall length of this assembly are specific to the routing path on the STX55 platform — an incorrect length or diameter will compromise flow rate and system pressure. When a hose degrades, swells, or develops a leak, hydraulic performance drops quickly, which can manifest as sluggish blade adjustment, inconsistent drive response, or fluid contamination of surrounding components.
