Multiquip 22478 Hose Assembly 1/4 ID x 22.50 4FJ Straight Ends

The Multiquip 22478 is a genuine OEM Hose Assembly 1/4 ID x 22.50 4FJ Straight Ends designed for the STXD6i and HTXD6i hydrostatic ride-on power trowels. As a factory-sourced component, it delivers the exact dimensions, end fittings, and pressure rating specified for these machines — no guesswork on compatibility. Verified fitment covers the STXD6i and HTXD6i series, making this the straightforward choice when servicing the hydraulic system on either model. Order part number 22478 directly from DHS Equipment to keep your trowel operating at spec.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact internal diameter, length, and end-fitting specifications for hydraulic circuit integrity on ride-on trowels.
• 4FJ Straight-End Fittings — Pre-terminated with matched straight JIC-style ends that connect directly to existing ports without adapter hardware.
• Confirmed Fitment — Engineered specifically for the STXD6i and HTXD6i hydrostatic ride-on power trowel models.
• Maintains Hydraulic System Pressure — A correctly sized and properly terminated hose keeps hydraulic fluid routed at the right flow rate, supporting consistent blade pitch control and drive response.
• Hydraulic Leak Prevention — A worn or cracked hose can cause fluid loss, erratic blade response, and potential contamination of the hydraulic circuit; replacing with part 22478 restores a sealed, leak-free connection.

This hose assembly is part of the hydraulic plumbing circuit on the STXD6i and HTXD6i ride-on trowels. Its role is to carry pressurized hydraulic fluid between components — typically between the pump, control valves, and actuators that govern blade pitch and machine movement. The 1/4-inch internal diameter and 22.50-inch length are sized to maintain the correct flow velocity for the circuit it serves. When a hydraulic hose deteriorates, cracks, or develops a leak at the end fittings, fluid pressure drops, leading to sluggish or inconsistent blade control and potential damage to downstream hydraulic components.
