The Multiquip 21081 is a genuine OEM Hose 3/4 ID x 54.5 Megavac designed for the STX55J6 and STX55Y6 super-sized hydrostatic ride-on power trowels. As a direct OEM part, 21081 is manufactured to the exact dimensions and material standards required by these machines, ensuring a proper, trouble-free installation. Sourced directly through authorized Multiquip channels, this hose delivers the consistency and durability that operators depend on during demanding finishing work. If you are servicing an STX55J6 or STX55Y6, this is the correct OEM replacement hose for the job.
Key Features
- Genuine OEM Construction — Manufactured to the exact inner diameter and length specification required by the Megavac system, ensuring consistent flow and a secure seal at both connection points.
- Exact-Length Replacement — At 54.5 inches with a 3/4-inch inner diameter, this hose routes and connects precisely as the original, with no trimming or adaptation needed.
- Confirmed STX55 Series Fitment — Verified for the STX55J6 and STX55Y6 super-sized hydrostatic ride-on trowels; always cross-reference part number 21081 before ordering.
- Maintains Vacuum System Integrity — A correctly sized and undamaged hose keeps the Megavac system drawing properly; a cracked or collapsed hose causes loss of suction and inconsistent trowel performance.
- Fuel and Fluid System Safety — Using the OEM-specified hose material guards against deterioration from fluid exposure, reducing the risk of leaks in an operating machine.
The Megavac hose on an STX-series ride-on trowel carries vacuum or fluid through a routed path within the machine's system, maintaining the pressure differential or fluid transfer that the Megavac circuit depends on. When this hose cracks, collapses, or loses its seal at either end, the system can no longer function as intended, leading to erratic operation or a complete loss of function in the affected circuit. Replacing a worn hose with the correct OEM part restores system performance and prevents secondary damage caused by operating with a compromised line.
