As a direct Multiquip OEM component, 21081-001 is manufactured to the exact dimensional and material specifications required for proper installation and dependable operation.

Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact inner diameter and length specification, ensuring the hose seats and seals properly within the vacuum or fluid routing system of your trowel.
- Exact-Fit Replacement — The 3/4-inch inner diameter and 54.4-length spec match the original routing path on the STX55 platform, allowing direct installation without modification to hose clamps or fittings.
- Confirmed STX55 Fitment — Verified for STX55J6 and STX55Y6 hydrostatic ride-on trowels, so you can order with confidence that this is the correct hose for your machine.
- Maintains Hydraulic and Vacuum Integrity — A correctly sized and properly seated hose preserves system pressure and flow; a cracked, collapsed, or undersized hose can cause erratic blade pitch response or hydraulic system inefficiency.
- Fluid and Pressure Compatibility — Sourced as a genuine OEM part, this hose is suited to the operating pressures and fluid types present in the STX55 series trowel's onboard systems, reducing the risk of premature hose failure.
The Hose 3/4 ID x 54.4 Megavac serves as a routed fluid or vacuum transfer line within the STX55 series ride-on trowel's hydraulic or auxiliary system. This type of hose carries fluid or vacuum pressure between components, and its inner diameter and length are critical to maintaining proper system flow and pressure balance. When a hose of this type cracks, collapses, or loses its seal at either end, the system it serves can develop pressure loss, fluid leaks, or inconsistent performance — making prompt replacement with the correct OEM part essential to restoring full machine function.
