The Multiquip 21083 Hose Assembly.38Id X 54.5Lg 45 One End is a genuine OEM hydraulic hose assembly designed for the STX55J6 and STX55Y6 super-sized hydrostatic ride-on power trowels. As a direct OEM replacement, this assembly carries the exact dimensional specifications — including the.38-inch inner diameter, 54.5-inch length, and 45-degree end fitting — ensuring it routes and connects precisely as the original. Sourced directly through the Multiquip OEM supply chain, part 21083 meets the original engineering requirements for these machines. If you are servicing an STX55J6 or STX55Y6, confirming this part number against your machine's parts manual before ordering is always recommended.
Key Features
- OEM-Specified Hydraulic Hose Construction — Built to the exact inner diameter and pressure requirements of the STX55 hydraulic system, not a generic hose substitute.
- Correct 45-Degree End Fitting — The single 45-degree end fitting matches the original routing geometry, allowing the hose to seat and seal properly at the connection point without stress on adjacent fittings.
- Exact Length Matched to STX55 Routing — At 54.5 inches, this hose spans the intended run without slack or tension that could cause premature wear or chafing against the machine frame.
- Confirmed Fitment for STX55J6 and STX55Y6 — Verified for Multiquip super-sized hydrostatic ride-on trowel models STX55J6 and STX55Y6.
- Hydraulic Integrity Under Working Conditions — A worn or leaking hose in the STX55 hydraulic circuit can cause loss of blade pitch control or drive response; replacing with the correct OEM assembly restores full system pressure and control.
Hydraulic hose assemblies carry 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, length, and end fitting angle of each hose are engineered to maintain the correct flow rate and routing path within the machine's hydraulic circuit. When a hose develops a leak, kink, or fitting failure, hydraulic pressure drops and the operator loses precise control over blade angle and traction — making timely replacement with the correct OEM part critical to safe and consistent trowel operation.
