The Multiquip 12144 Suction Hose 3/4 100R4 9 LNG is a genuine OEM replacement built for STH series hydrostatic ride-on trowels. This is a direct OEM part sourced through Multiquip's authorized supply chain, ensuring the hose meets the original hydraulic system specifications for your machine. Confirmed fitment for STH hydrostatic ride-on trowel models makes 12144 a straightforward, confidence-inspiring choice when it's time to restore hydraulic performance.

Key Features

  • OEM-Grade Hydraulic Construction — Built to the 100R4 hose standard, delivering the correct pressure rating, inner bore diameter, and reinforcement layering required for hydraulic suction service in ride-on trowel applications.
  • Direct Hydraulic Line Replacement — Designed to connect directly into the existing hydraulic suction circuit of STH series machines, matching the original 3/4-inch bore and 9-unit length specification for a clean swap.
  • Confirmed STH Series Fitment — Verified for use on Multiquip STH hydrostatic ride-on trowels, so you can order with confidence that this part is the correct component for your machine.
  • Maintains Hydraulic Suction Integrity — A properly functioning suction hose sustains consistent hydraulic fluid draw to the pump. A cracked, collapsed, or deteriorated hose introduces air into the system, causing erratic blade pitch response and potential pump damage.
  • Genuine Multiquip OEM Part — Supplied as an authentic Multiquip component, meaning material grades, reinforcement specification, and end fittings match what the machine left the factory with.

The suction hose in a hydrostatic ride-on trowel carries hydraulic fluid from the reservoir to the hydraulic pump, maintaining a steady, low-restriction flow that keeps the pump primed and the system pressurized. In a ride-on trowel, the hydraulic circuit governs both blade pitch adjustment and machine drive, so any degradation in the suction line directly affects how precisely the operator can control the trowel. When this hose softens, collapses internally, or develops a leak, the pump starves for fluid, leading to inconsistent blade response, overheating, and accelerated pump wear — making timely replacement critical to keeping the machine working accurately on the slab.
