Multiquip 21100 Hose Assembly .5 ID x 19" with 45° End - OEM Replacement Part

This hydraulic hose assembly delivers pressurized fluid to the independent drive motors on ride-on power trowels, enabling precise speed control and steering response. The 0.5-inch inner diameter and 19-inch length with 45-degree fitting at one end are engineered specifically for the compact routing requirements of STX-series machines.

Because the two hydraulic drive motors on STX-series trowels operate independently of each other, maintaining proper hydraulic flow through intact hoses is critical for balanced operation. As noted in Multiquip maintenance procedures, if the unit's steering becomes difficult to control or one spider spins noticeably faster or slower than the other, hydraulic system issues including compromised hoses may be the cause. Multiquip recommends checking trowel speed balance at least once annually as part of routine maintenance.

Failed or degraded hydraulic hoses can result in uneven blade speed, loss of foot pedal control responsiveness, and difficulty maneuvering during finishing operations. This genuine OEM hose assembly ensures proper fit and pressure ratings for reliable hydraulic performance.
