The Multiquip 21114 Straight Fitting 6Fo-6Mo is a genuine OEM hydraulic fitting designed for Whiteman ride-on power trowel models including the STX55J6, STX55Y6, STXD6i, HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, and HTXG6DF series. As a direct OEM component, part 21114 is manufactured to the exact thread form and port dimensions required by the hydraulic circuit in these machines. Sourcing the correct fitting ensures a leak-free, properly rated hydraulic connection that keeps your trowel running at full output. DHS Equipment stocks genuine Multiquip OEM parts so you get the right component the first time.
Key Features
- Genuine OEM Thread Specification — Manufactured to the exact 6Fo-6Mo thread form and seat angle required for a pressure-rated, leak-free hydraulic connection on Whiteman ride-on trowels.
- Direct Hydraulic Line Replacement — Replaces the original fitting at the hydraulic port without reworking hose ends or adapting line sizes, maintaining the original plumbing geometry.
- Broad Ride-On Trowel Compatibility — Confirmed fitment across STX55J6, STX55Y6, STXD6i, HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, HHXDF4-DF5, and HTXG6DF models.
- Hydraulic System Integrity — A correctly seated fitting maintains circuit pressure for responsive blade pitch and drive control; a degraded or cross-threaded fitting can cause pressure loss, fluid leaks, and erratic trowel behavior.
- Fluid Leak Prevention — Proper sealing at hydraulic connection points is critical on ride-on trowels where hydraulic fluid leaks near rotating blade assemblies create a slip and fire hazard.
A straight hydraulic fitting serves as the threaded junction between a hydraulic hose or tube and a port on a valve, pump, or actuator within the machine's hydraulic circuit. On hydrostatic ride-on trowels like the STX and HTX series, the hydraulic system governs both blade pitch adjustment and machine propulsion, so every fitting in the circuit must hold rated working pressure without seeping. When a fitting corrodes, cracks, or loses thread engagement, hydraulic pressure drops, fluid escapes, and the operator loses precise control over blade angle and forward drive — directly affecting finish quality and operator safety. Replacing a damaged fitting promptly with the correct Multiquip 21114 restores full hydraulic integrity and keeps the trowel performing as designed.
