The Multiquip 18058SK is a genuine OEM Directional Valve Seal Kit designed for Whiteman hydraulic power buggies, including the WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH21EPA, WBH-21EF, and WBH-21EFP series. As a direct OEM part sourced from Multiquip, the 18058SK is engineered to restore the directional valve to original operating condition with seals that match the exact material grade and dimensional tolerances of the factory-installed components. This kit covers the complete seal set for the directional valve, making it the correct choice for a thorough hydraulic service rather than a partial fix. Confirm your model against the fitment list above before ordering to ensure this is the right kit for your machine.
Key Features
- OEM-Grade Seal Materials — Seals are manufactured to the same compound and compression specifications as the originals, maintaining hydraulic pressure integrity under working load conditions.
- Complete Valve Seal Coverage — Includes the full set of seals required for the directional valve, so one kit handles the entire service without sourcing individual components separately.
- Direct-Fit for WBH-16 and WBH-21 Series — Engineered specifically for Whiteman hydraulic power buggies across the WBH-16 and WBH-21 model families, including AWD and foam-filled-tire variants.
- Restores Hydraulic Directional Control — A worn or leaking directional valve seal causes sluggish or erratic dump and drive response; replacing the seal set brings steering and hydraulic function back to spec.
- Genuine Multiquip OEM Part — Supplied under part number 18058SK directly through the Multiquip parts network, ensuring traceability and correct fitment documentation.
The directional valve in a hydraulic power buggy controls the flow and routing of hydraulic fluid to the dump, drive, and steering circuits. Seals within the valve prevent internal and external fluid leakage, maintaining the pressure differential needed for responsive, consistent hydraulic operation. When these seals deteriorate — due to heat cycling, age, or contaminated fluid — the valve loses the ability to hold pressure efficiently, resulting in slow dump response, hydraulic drift, or visible fluid leaks at the valve body. Replacing the full seal set with the Multiquip 18058SK Directional Valve Seal Kit restores proper hydraulic circuit function and prevents further damage to downstream components.
