Multiquip 21334 Hose Assembly 1/2 ID x 26.50 -10FJ Straight Ends

The Multiquip 21334 Hose Assembly 1/2 ID x 26.50 -10FJ Straight Ends is a genuine OEM component designed for STX55J6, STXD6i, HTXD6i, and STX55Y6 hydrostatic ride-on power trowels. As a direct OEM replacement, this hose assembly meets the exact specifications set by Multiquip for hydraulic system integrity on these machines. Sourced directly through authorized channels, the 21334 ensures a correct, confident fit for technicians servicing this series of finish trowels. Verify your model against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Hydraulic Integrity — Built to Multiquip's original pressure and flow specifications for the hydraulic circuits on hydrostatic ride-on trowels, ensuring the hose performs as the system was engineered to expect.
• Straight -10FJ End Fittings — The straight female JIC end fittings connect directly to mating ports without adapters, simplifying installation on the STX and HTX hydraulic plumbing.
• Correct Hose Length and Bore — At 1/2 inch ID and 26.50 inches in length, this assembly matches the original routing path precisely, eliminating the need to source and fabricate a custom replacement hose.
• Fits Key Hydrostatic Trowel Models — Confirmed fitment for STX55J6, STXD6i, HTXD6i, and STX55Y6 Whiteman ride-on power trowels.
• Hydraulic System Reliability — A degraded or leaking hose in a hydrostatic trowel can cause loss of blade pitch control and drive response; replacing with the correct OEM assembly restores full system pressure and smooth operator control.
• Pressure System Safety — Hydraulic hose failures under operating pressure present a fluid injection hazard; using the OEM-specified hose assembly maintains the rated pressure containment designed into the machine's hydraulic circuit.

The hose assembly on a hydrostatic ride-on power trowel carries pressurized hydraulic fluid between the pump, control valves, and actuators that govern both blade pitch adjustment and machine drive. Without a properly functioning hose, hydraulic pressure drops, leading to sluggish or unresponsive blade control and reduced troweling consistency on the concrete surface. Over time, hose inner liners can degrade, swell, or crack, causing internal flow restriction or external leakage that compromises the entire hydraulic circuit.
