Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Multiquip's exact thread and port specifications for the 4MJ 4MJ 4FJ configuration, ensuring proper sealing under hydraulic system pressures.
- Drop-In Hydraulic Connection — Matches the original port geometry and thread pitch of the STXD6i and HTXD6i hydraulic plumbing, allowing straightforward installation without line modification.
- Confirmed Fitment for STXD6i and HTXD6i — Verified for Multiquip's super-sized and heavy-duty hydrostatic ride-on trowel series powered by the Yanmar diesel engine.
- Leak-Free Hydraulic Integrity — A correctly installed tee run fitting maintains full hydraulic flow and pressure to blade pitch and drive circuits; a failed or mismatched fitting can cause pressure loss and erratic trowel control.
- Sourced Through Authorized Distribution — Supplied by DHS Equipment as an authorized Multiquip dealer, backed by accurate part number verification against current OEM parts documentation.
A tee run fitting is a three-port hydraulic connector that allows a single fluid line to branch into two directions while maintaining continuous flow through the run ports. In a hydrostatic ride-on trowel like the STXD6i or HTXD6i, fittings of this type are used throughout the hydraulic plumbing that controls blade pitch adjustment and machine drive. When a fitting cracks, cross-threads, or develops a leak at its seating surface, hydraulic fluid loss can cause inconsistent blade response, reduced drive power, and potential contamination of surrounding components — making prompt replacement with the correct OEM part essential to keeping the trowel performing to specification.
