Multiquip 21111 Hose Assembly .38ID X 38LG - OEM Replacement Part for Trowels

This hydraulic hose assembly delivers pressurized fluid to critical trowel arm systems, maintaining proper blade pitch control and preventing the bouncing, rolling, or uneven swirl patterns that indicate hydraulic failure. The 0.38-inch inner diameter and 38-inch length with pre-installed end fittings ensure proper flow rates and precise fitment without field modifications.

Hydraulic system integrity is essential for trowel arm performance. When hoses degrade or fail, symptoms include inconsistent blade angles across the spider assembly, trowel bounce during finishing operations, and loss of arm height control. The technical manual specifies that trowel arm bushings should have no more than 1/8-inch (3.2mm) of travel at the arm tip—excessive movement often indicates loss of hydraulic pressure from failed hoses before bushing wear becomes apparent.

This assembly maintains the hydraulic pressure necessary to keep all blades at uniform pitch angles as measured at the spider, which is critical for producing smooth, professional concrete finishes. Pre-assembled with proper end fittings to eliminate leak points and ensure correct connections.
