The Multiquip 3283 Straight Fitting -4FJ x -4FP is a genuine OEM hydraulic fitting designed for Whiteman ride-on power trowels, ride-on roller screeds, and ride-on power float models including HHXDF4-DF5, HTXG6DF, STXDF, WRSPUDF, WRS5200, and PRX. As a direct OEM replacement, 3283 delivers exact dimensional conformance to the original hydraulic plumbing layout, ensuring a secure, leak-free connection at installation. Sourced directly through authorized Multiquip distribution, this fitting is built to the same specification as the part it replaces, so you can be confident in the integrity of your hydraulic circuit from day one.
Key Features
- OEM-Spec Thread Engagement — Machined to the correct -4FJ female JIC and -4FP female pipe thread dimensions, ensuring full thread engagement and a pressure-rated seal without modification.
- Straight-Body Configuration — The inline -4FJ x -4FP geometry matches the original hydraulic line routing on supported machines, allowing direct swap-in without rerouting hoses or adapters.
- Broad Ride-On Equipment Fitment — Confirmed fit for HHXDF4-DF5, HTXG6DF, STXDF, WRSPUDF, WRS5200, and PRX models, covering Whiteman ride-on power trowels, roller screeds, and hybrid power floats.
- Hydraulic System Integrity — A correctly seated fitting maintains consistent hydraulic pressure across the blade pitch and drive circuits; a failing or mismatched fitting can cause pressure loss, erratic blade response, or fluid leaks that compromise machine control.
- Leak-Free Sealing Under Pressure — The JIC flare-seat and pipe-thread interfaces are designed to hold a positive seal under the operating pressures of ride-on trowel and screed hydraulic systems, supporting safe and consistent machine operation.
A straight hydraulic fitting like the Multiquip 3283 serves as the threaded junction between hydraulic hose ends and ported components within the machine's hydraulic circuit. The -4FJ end uses a 37-degree JIC flare seat to form a metal-to-metal seal, while the -4FP end threads into a female pipe port, together routing pressurized fluid to the actuators, motors, or valves that control blade pitch and drive function. When a fitting corrodes, cross-threads, or develops a leak, hydraulic pressure drops and the operator loses precise control over the trowel blades or screed drive — making prompt replacement critical to consistent finishing results and safe operation.
