Multiquip 22391 Hose Assembly 5/8ID x 55.50 12FJx10FJ45 5K

The Multiquip 22391 is a genuine OEM Hose Assembly 5/8ID x 55.50 12FJx10FJ45 5K designed for the STXD6i and HTXD6i Whiteman ride-on power trowels. Sourced directly from Multiquip, this assembly matches the original equipment specification — ensuring a correct, trouble-free installation without adaptation. Keeping the hydraulic circuit intact with the right hose assembly is critical to consistent blade pitch control and drive performance on these hydrostatic trowel models. If you are confirming fitment, reference model codes STXD6i and HTXD6i before ordering.

Key Features

• Genuine OEM Construction — Built to Multiquip's original pressure and flow specifications for a 5,000 PSI-rated hydraulic hose assembly, so the hydraulic system operates exactly as engineered.
• Correct End Fittings — Configured 12FJ straight x 10FJ 45-degree JIC fittings that mate directly to the factory hydraulic ports, eliminating guesswork at installation.
• Verified Fitment — Confirmed for Whiteman ride-on power trowel models STXD6i and HTXD6i; verify your model code before ordering to ensure an exact match.
• Pressure-Rated Integrity — Rated to 5K (5,000 PSI), matching the demands of the hydrostatic drive system and blade pitch circuit on these trowels.
• Protects Hydraulic System Reliability — A worn or degraded hose assembly can cause pressure loss, sluggish blade response, or uncontrolled fluid leaks; replacing with the correct OEM part restores full hydraulic circuit function.

A hydraulic hose assembly like the Multiquip 22391 is a load-bearing fluid conduit that carries pressurized hydraulic oil between components in the trowel's hydrostatic drive and blade pitch control system. The hose must maintain a sealed, pressure-stable path under continuous flexing and high operating pressures — any degradation in the hose wall or fitting connection leads to pressure drop, erratic blade pitch, or hydraulic fluid loss. Using the correct OEM assembly with properly matched end fittings and pressure rating ensures the hydraulic system performs consistently and avoids secondary damage to pumps, valves, or actuators downstream.
