The Multiquip 21819 is a genuine OEM Hose Assembly.75 In ID x 17.5 In 100R1 designed for HTX44-series hydrostatic ride-on power trowels, including the HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5. As a direct Multiquip OEM part, 21819 is manufactured to the exact dimensions and pressure ratings required by the hydraulic system in these machines. DHS Equipment sources this part directly through authorized channels, so you can order with confidence knowing you are receiving the correct component. Verify your model code against the fitment list before ordering to ensure a proper match.
Key Features
- OEM-Spec Hydraulic Hose Construction — Built to the 100R1 hose standard, this assembly delivers the wall strength and pressure handling required for the hydraulic circuits in HTX44-series trowels.
- Exact-Dimension Replacement — At .75 in ID and 17.5 in in length with -12FJX to -16FJ end fittings, this hose assembly installs directly into the original routing without cutting or adapting.
- Confirmed Fitment for HTX44 Series — Verified for the HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 hydrostatic ride-on trowels, covering both Kubota and Yanmar engine variants.
- Maintains Hydraulic System Integrity — A worn or cracked hose leads to hydraulic fluid loss, erratic blade pitch control, and loss of drive function. Replacing with the correct OEM hose restores full system pressure and responsiveness.
- Genuine Multiquip Part — Supplied as an original equipment component under part number 21819, ensuring the hose material, fittings, and assembly tolerances match what the machine left the factory with.
The Hose Assembly .75 In ID x 17.5 In 100R1 is a hydraulic fluid transfer line within the hydrostatic drive or blade pitch circuit of the HTX44-series ride-on trowel. It routes pressurized hydraulic fluid between key components, and the 100R1 rating indicates a single-wire-braid reinforced construction suited to the operating pressures found in these machines. When this hose develops a leak, weeps fluid, or collapses internally, the hydraulic system loses the pressure needed to control blade pitch or machine travel, which can result in uneven finishing and potential loss of operator control. Replacing a degraded hose promptly with the correct OEM assembly keeps the hydraulic circuit operating at the pressures the system was engineered to deliver.
