Multiquip 21146 Hose Assembly .5Idx25.5 Lg 45 One End

The Multiquip 21146 Hose Assembly.5Idx25.5 Lg 45 One End is a genuine OEM hydraulic hose assembly designed for the HTX44 series hydrostatic ride-on power trowels. This direct-replacement hose fits the HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 models, ensuring the correct inner diameter, length, and 45-degree end configuration for a proper installation every time. As an authentic Multiquip OEM part, the 21146 is built to the same specifications as the original component that left the factory. Keep this part on hand for scheduled maintenance or emergency hydraulic line service to keep your HTX44 trowel running at full capacity.

Key Features

• Genuine OEM Hose Construction — Manufactured to Multiquip's original pressure rating and inner diameter specification, maintaining the hydraulic integrity of the HTX44 system.
• Correct 45-Degree End Configuration — The pre-formed 45-degree fitting on one end matches the original routing geometry, allowing the hose to seat and seal correctly without rework.
• HTX44 Series Fitment — Confirmed fit for HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 hydrostatic ride-on trowels.
• Preserves Hydraulic System Performance — A correctly functioning hose maintains consistent fluid flow and pressure to the drive and blade-pitch hydraulics; a cracked or failing hose leads to pressure loss, erratic blade response, and fluid leaks.
• Hydraulic Line Safety — A compromised hydraulic hose can cause sudden loss of blade or drive control on a ride-on trowel; replacing worn lines with the correct OEM part maintains safe, predictable machine operation.

A hydraulic hose assembly routes pressurized fluid between the pump, control valves, and actuators that govern blade pitch and machine drive on hydrostatic ride-on trowels. The specific inner diameter and hose length of the 21146 are engineered to maintain the correct flow rate and pressure drop within the HTX44 hydraulic circuit. When a hose degrades — through cracking, abrasion, or fitting failure — hydraulic pressure drops, causing sluggish or uneven blade response, oil contamination risks, and potential loss of drive control.
