The Multiquip 22390 Hose Assembly 5/8 ID x 79.50 12FJ Straight Ends is a genuine OEM hydraulic hose assembly designed for the STXD6i and HTXD6i hydrostatic ride-on power trowels. As a direct OEM replacement, this hose assembly is manufactured to the exact dimensions and end-fitting specifications required by these machines, ensuring a correct, leak-free installation. Verify your model code against STXD6i and HTXD6i before ordering to confirm fitment. Sourced directly through authorized Multiquip distribution, part number 22390 is the correct factory-specified component for this application.
Key Features
- Genuine OEM Construction — Built to the exact hose ID, length, and end-fitting specification Multiquip engineers require for the hydraulic circuit on these trowels — not a generic hose adaptation.
- Correct 5/8 ID x 79.50 Length with 12FJ Straight Ends — The straight JIC female swivel ends seat flush against the mating fittings in the system, allowing clean, straight-line installation without routing stress.
- Fits STXD6i and HTXD6i Ride-On Trowels — Confirmed fitment for Multiquip's super-sized and heavy-duty hydrostatic trowel models equipped with Yanmar diesel engines.
- Maintains Hydraulic System Integrity — A correctly specified hose sustains the operating pressure demanded by the hydrostatic drive and blade-pitch system; an undersized or worn hose risks pressure loss, erratic blade response, or drive failure mid-pour.
- Pressure-Side Safety Assurance — Hydraulic hose failures on ride-on trowels can release high-pressure fluid unexpectedly; using the OEM-specified assembly keeps the system within its rated pressure envelope.
This hose assembly carries hydraulic fluid between components within the hydrostatic drive or blade-pitch circuit of the ride-on trowel. It maintains the pressurized flow that allows the operator to control machine movement and blade angle consistently throughout a finishing pass. When a hose degrades — through cracking, fitting corrosion, or internal delamination — pressure drops and fluid contamination can cause sluggish or unpredictable trowel response, making smooth, even concrete finishing difficult and potentially damaging the hydraulic pump or motor over time.
