Multiquip 22403 Hose Assembly 5/8Idx22.0 4K 10-45X12-45 Ends

The Multiquip 22403 Hose Assembly 5/8Idx22.0 4K 10-45X12-45 Ends is a genuine OEM hydraulic hose assembly designed for the STXD6i hydrostatic ride-on power trowel. Sourced directly from Multiquip, this part carries the same specifications as the hose installed at the factory, ensuring a direct, leak-free connection without the guesswork of sourcing a generic substitute. The 22403 is purpose-built for the hydraulic circuit demands of the STXD6i platform, where consistent pressure delivery is critical to blade pitch control and machine drive performance. If your hose is cracked, weeping, or showing signs of abrasion wear, replacing it with the correct OEM part keeps the hydraulic system operating at spec.

Key Features

• OEM Hydraulic Rating: — Built to the 4K pressure specification required by the STXD6i hydraulic circuit, maintaining correct system pressure across the full operating range.
• Pre-Terminated with Correct End Fittings: — Supplied complete with 10-45 and 12-45 angled end fittings already installed, so the hose connects directly to existing ports without additional adapters or re-crimping.
• Confirmed Fitment for STXD6i: — Verified for Whiteman STXD6i hydrostatic ride-on power trowels; use part number 22403 to confirm compatibility before ordering.
• Maintains Hydraulic Integrity: — A worn or failing hose causes pressure loss in the hydraulic system, leading to sluggish blade response and inconsistent drive behavior on the finishing pass.
• Genuine Multiquip OEM Part: — Manufactured to the same material and dimensional standards as the original, ensuring consistent inner diameter, bend radius, and fitting torque values are preserved.

A hydraulic hose assembly like the Multiquip 22403 carries pressurized fluid between the pump, control valves, and actuators that govern blade pitch and machine movement on a hydrostatic ride-on trowel. The 5/8-inch inner diameter and 4,000 PSI working pressure rating are matched to the flow and pressure requirements of the STXD6i hydraulic system. When a hose deteriorates — through cracking, abrasion, or internal separation — hydraulic pressure drops, blade control becomes erratic, and in severe cases the system loses drive function entirely, bringing the finishing operation to a halt.
