The Multiquip 21161 Hose Assembly.5Idx44.5Lg 45 One End 90 End is a genuine OEM component designed for HTX44 series hydrostatic ride-on power trowels. This hose assembly is built to Multiquip's original specifications, ensuring correct fluid routing within the hydraulic system of your HTX44-series machine. Confirmed fitment covers the HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 models, making it a direct replacement for worn, cracked, or leaking factory hose assemblies on these units.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original hose specification, including correct inner diameter, overall length, and dual-angle end fittings (45° one end, 90° other end) for a proper hydraulic circuit connection.
- Angle-Specific End Fittings — The combination of a 45° fitting on one end and a 90° fitting on the other matches the original routing path inside the HTX44 hydraulic system, allowing the hose to seat correctly without binding or stress on the fittings.
- HTX44 Series Fitment — Verified for the HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 hydrostatic ride-on trowels — covering both Kubota and Yanmar engine variants in the HTX44 family.
- Hydraulic Integrity Protection — A deteriorated or leaking hose in this position can cause loss of hydraulic pressure, affecting blade pitch control and drive responsiveness. Replacing with part 21161 restores full system pressure and consistent trowel performance.
- Direct OEM Replacement — As a genuine Multiquip part, 21161 installs in place of the original without modification to existing fittings, brackets, or routing hardware on the HTX44 platform.
This hose assembly serves as a hydraulic fluid conduit within the HTX44 ride-on trowel's hydrostatic drive or blade-pitch control circuit. It carries pressurized hydraulic fluid between components, and the specific angle fittings at each end ensure the hose follows the designed routing path without placing mechanical stress on connected ports. When a hydraulic hose of this type cracks, swells, or develops a leak, the machine may lose blade control responsiveness or drive function — making timely replacement critical to keeping the trowel operating safely and consistently.
