The Multiquip 21082 Hose Assembly.38Id X 18Lg Str Ends is a genuine OEM hydraulic hose assembly designed for the STX55J6 and STX55Y6 Whiteman ride-on power trowels. As a direct OEM replacement, this hose assembly is manufactured to the same specifications as the original component, ensuring a proper, leak-free connection within the hydraulic system. Sourced directly through authorized Multiquip supply channels, part 21082 is the correct replacement when servicing STX55 series trowels equipped with John Deere or Yanmar diesel engines. DHS Equipment stocks genuine Multiquip OEM parts so you can get your machine back to work with confidence.
Key Features
- Genuine OEM Construction: — Manufactured to the original pressure rating and bore specification, ensuring consistent hydraulic flow and a reliable seal under operating conditions.
- Straight-End Fittings for Direct Connection: — Straight end configuration allows for straightforward installation into existing hydraulic ports without adapters or modification to the line routing.
- Confirmed Fitment for STX55 Series Trowels: — Verified for the STX55J6 and STX55Y6 hydrostatic ride-on power trowels, so you can order with confidence using part number 21082.
- Maintains Hydraulic System Integrity: — A correctly functioning hose assembly keeps hydraulic pressure stable across the blade pitch and drive circuits, supporting smooth, responsive trowel operation.
- Fluid Compatibility and Pressure Safety: — Hydraulic hose assemblies are rated for specific pressure ranges and fluid types; using the correct OEM-spec hose helps prevent burst failures and uncontrolled hydraulic release on a live machine.
A hydraulic hose assembly carries pressurized fluid between components in the trowel's hydrostatic drive and blade pitch control systems. On STX55 series ride-on trowels, these hoses are part of the closed-loop hydraulic circuit that allows the operator to adjust blade angle and machine direction with precision. When a hose develops a leak, cracks, or loses its end-fitting seal, hydraulic pressure drops and machine responsiveness suffers — and in severe cases, fluid loss can lead to component damage or create a slip hazard on the work surface.
