Multiquip 21055 Fitting 90° 16MO-16MO - OEM Replacement Part

This 90-degree hydraulic fitting connects critical hydraulic lines in the blade pitch adjustment system of STX-series ride-on trowels, enabling precise control of blade angle during concrete finishing operations. The 16MO-16MO configuration ensures proper hydraulic flow between components that control blade pitch via the electric rocker switches and foot pedal controls.

In STX-series trowels, the blade pitch adjustment system is essential for achieving consistent finishing quality and preventing issues like bouncing, rolling, or uneven swirl patterns in concrete. The hydraulic system allows operators to synchronize pitch on both left and right blade assemblies independently using the blade pitch rocker switches. Maintaining proper hydraulic connections ensures responsive pitch control, which is critical when adjusting blades from flat positions during setup to the precise angles needed for quality finishing work.

Failed or leaking hydraulic fittings can result in loss of blade pitch control, inconsistent finishing performance, and potential hydraulic fluid contamination of the work area. Regular inspection of hydraulic connections during routine maintenance helps prevent these issues.
