Key Features

• Genuine OEM Tube Management: — Manufactured to Multiquip's original specification for secure, rattle-free routing of 3/8-inch hydraulic or fluid tubing on ride-on trowel platforms.
• Paired Clamp Configuration: — Supplied as a pair, matching the factory installation requirement so both clamp positions are replaced simultaneously for consistent hold and alignment.
• Direct Drop-In Installation: — Designed to mount in the original clamp location with existing hardware, requiring no drilling, trimming, or adaptation.
• Broad HTX and STX Series Fitment: — Confirmed for HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, STX55J6, STX55Y6, and STXD6i Whiteman hydrostatic ride-on trowels.
• Prevents Line Wear and Chafing: — Properly secured tubing resists vibration-induced abrasion; a missing or cracked clamp allows lines to rub against the frame, risking leaks and unplanned stoppages.

A tube clamp holds hydraulic or fluid lines firmly against the machine frame, keeping them routed away from moving components, heat sources, and sharp edges. On a hydrostatic ride-on trowel, where hydraulic circuits control both blade pitch and drive functions, secure line management is essential to maintaining consistent pressure and protecting hose integrity. When a clamp breaks, cracks, or goes missing, the unsupported line is exposed to constant vibration and contact wear, which can accelerate hose degradation and lead to hydraulic fluid loss over time.
