The Multiquip 3366 45 12 Barb 12Mo Fitting is a genuine OEM hydraulic fitting designed for Whiteman ride-on power trowel models including the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, STXD6i, and HTXD6i. Sourced directly from Multiquip, part 3366 is manufactured to the same specifications as the original component installed at the factory, ensuring a proper connection within the machine's hydraulic circuit. If your ride-on trowel is showing signs of hydraulic fluid seepage or pressure loss at a fitting junction, replacing the worn fitting with this genuine part restores the integrity of the system. DHS Equipment stocks this OEM part to help keep your Whiteman hydrostatic trowel running at full capacity.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Multiquip's original material and dimensional specifications, ensuring correct sealing performance under operating hydraulic pressures found in ride-on trowel systems.
- 45-Degree Barb Configuration — The angled 45-degree barb-to-male orientation allows the fitting to route hydraulic lines in tight spaces without stressing the hose or adjacent components.
- Broad HTX and STX Series Compatibility — Confirmed fitment for HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, STXD6i, and HTXD6i Whiteman hydrostatic ride-on trowels.
- Leak-Free Hydraulic Performance — A correctly seated fitting maintains system pressure, enabling smooth blade pitch adjustment and consistent drive response across the trowel's full operating range.
- Hydraulic System Safety — A failed or improperly rated fitting can cause uncontrolled pressure loss or hydraulic fluid leakage, creating slip hazards and unpredictable machine behavior on the finishing deck.
Hydraulic fittings like the Multiquip 3366 serve as the sealed connection points between hoses, lines, and hydraulic components throughout the trowel's drive and blade-pitch control circuit. A 45-degree barbed fitting routes pressurized fluid at an angle, reducing hose bend stress while maintaining a secure, leak-resistant joint. When a fitting cracks, corrodes, or loses its sealing surface, hydraulic pressure drops, blade response becomes inconsistent, and fluid can escape onto work surfaces — making prompt replacement with a correct OEM part essential to safe, effective operation.
