Multiquip 21296 Hose Assembly 3/4 ID x 15.25 90 End R4

The Multiquip 21296 is a genuine OEM Hose Assembly 3/4 ID x 15.25 90 End R4 designed for STX55 and HTX44 series hydrostatic ride-on power trowels. As a direct OEM replacement, part 21296 is manufactured to the same specifications as the original component, ensuring a correct, trouble-free installation on compatible Whiteman ride-on trowel models. Confirmed fitment includes the STX55J6, STX55Y6, HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5. If you are servicing a hydrostatic trowel in the STX55 or HTX44 family, this is the correct hose assembly to specify.

Key Features

• OEM-Grade Hose Construction — Built to the same pressure rating and material grade as the original, maintaining proper hydraulic integrity throughout the trowel's operating range.
• 90-Degree End Configuration — The factory 90-degree end fitting allows the hose to route and seat correctly in tight hydraulic plumbing runs without forcing bends or stressing adjacent fittings.
• Confirmed STX55 and HTX44 Fitment — Verified for the STX55J6, STX55Y6, HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5, covering multiple engine configurations within these two hydrostatic trowel families.
• Hydraulic System Performance — A correctly sized and routed hose keeps blade pitch and drive response precise; a cracked, swollen, or undersized hose can cause sluggish hydraulic response or loss of blade control.
• Direct OEM Part Number — Ordering by Multiquip part number 21296 eliminates guesswork and ensures the correct hose length, ID, and end-fitting style reach your machine the first time.

This hose assembly is part of the hydraulic circuit that controls blade pitch and drive function on Multiquip hydrostatic ride-on power trowels. The 3/4-inch internal diameter and 90-degree end fitting are sized and shaped to route hydraulic fluid at the correct flow rate and pressure between system components, keeping trowel blade angle response smooth and consistent. When a hydraulic hose deteriorates — through cracking, swelling, or fitting failure — fluid pressure drops, blade control becomes inconsistent, and the risk of a hydraulic leak increases, making timely replacement with the correct OEM part essential for safe, efficient finishing work.
