Multiquip 20911 Clamp 1.13 OD Tube Hydraulic Trowel

The Multiquip 20911 is a genuine OEM Clamp 1.13 OD Tube Hydraulic Trowel designed for WRS5200DFPU, WRS5200, WRSPUDF, and STX6H series equipment. As a direct Multiquip OEM part, 20911 is manufactured to the same specifications as the original component installed at the factory, ensuring a correct and consistent fit in the hydraulic line routing system. This clamp is a straightforward drop-in replacement that restores proper tube retention without requiring fabrication or adaptation. If you are servicing a Whiteman ride-on roller screed or an STX6H hydrostatic trowel, part 20911 is the correct clamp for this application.

Key Features

• Genuine OEM Clamp Integrity — Manufactured to Multiquip OEM specifications, this clamp maintains the correct 1.13-inch outside diameter grip needed to hold hydraulic tubing securely without distortion or crushing.
• Direct Bolt-In Replacement — Matches the original mounting hole pattern and clamp profile, allowing straightforward installation on the existing bracket without reworking the surrounding hardware.
• Broad Fitment Coverage — Compatible with WRS5200DFPU, WRS5200, WRSPUDF, and STX6H models, covering both Whiteman ride-on roller screed and hydrostatic trowel applications.
• Hydraulic Line Stability — Keeps hydraulic tubing positioned and vibration-dampened during operation; a loose or failed clamp allows tubes to shift under pressure cycling, accelerating wear on fittings and hose ends.
• Fuel and Hydraulic System Safety — Correctly secured hydraulic tubing reduces the risk of chafing, fatigue cracking, or unexpected line separation on high-cycle ride-on equipment.

A tube clamp holds hydraulic lines firmly against the machine's frame or designated routing brackets, preventing movement caused by engine vibration and hydraulic pressure pulses. When a clamp fails or goes missing, the unsupported tubing flexes repeatedly with each pressure cycle, which gradually fatigues the hose or hard line at its fittings and can lead to leaks or sudden line failure. Keeping the correct clamp — sized precisely for the 1.13-inch OD tubing used in these machines — is a low-cost maintenance step that protects the integrity of the entire hydraulic circuit.
