The Multiquip 3225 is a genuine OEM Straight -6MORFS x -6MORFS Bulkhead Fitting designed for Whiteman and Multiquip ride-on power trowel models including the HTX6H, STX6H, HHXDF4-DF5, HTXG6DF, and PRX series. As a direct OEM component, part 3225 is produced to the same specification as the original hardware installed at the factory, ensuring a correct, trouble-free installation in the hydraulic circuit of your trowel. DHS Equipment stocks this fitting so you can get your machine back in service without hunting for a cross-reference or a substitute. Confirm your model against the fitment list before ordering to ensure this is the right part for your machine.
Key Features
- OEM-Spec Thread Form and Sealing Surface — Manufactured to the exact -6MORFS male O-ring face seal thread specification on both ports, so the fitting seats and seals correctly without modification to fittings or lines.
- Bulkhead-Through Design — The bulkhead configuration allows the hydraulic line to pass cleanly through a panel or chassis wall, maintaining a routed, protected hydraulic circuit inside the trowel frame.
- Confirmed Fitment Across Multiple Trowel Platforms — Part 3225 is a verified OEM fit for HTX6H, STX6H, HHXDF4-DF5, HTXG6DF, and PRX ride-on power trowels, covering both hydrostatic and hybrid series machines.
- Hydraulic Integrity Under Working Pressure — A correctly installed bulkhead fitting keeps the hydraulic system sealed and at operating pressure; a leaking or damaged fitting causes pressure loss that directly affects blade pitch control and drive response.
- Direct OEM Replacement — Sourced from Multiquip as a genuine OEM part, this fitting installs in place of the original with no rework to adjacent lines or fittings required.
A bulkhead fitting is a hydraulic connector designed to mount through a panel or structural wall, creating a fixed, leak-free pass-through point for a hydraulic line. On ride-on power trowels, these fittings are used to route hydraulic fluid between the engine-driven pump, the blade pitch actuators, and the drive system while keeping the lines organized and protected within the machine frame. When a bulkhead fitting cracks, strips, or develops a leak at the O-ring face seal, hydraulic fluid escapes under pressure — reducing system performance, contaminating surrounding components, and ultimately causing loss of blade control or drive function until the fitting is replaced.
