Multiquip 18064SK Dump Valve Seal Kit

The Multiquip 18064SK is a genuine OEM Dump Valve Seal Kit designed for Whiteman hydraulic power buggies, including the WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, and WTB-16. As a factory-sourced replacement, this kit delivers the exact seals required to restore proper dump valve function and maintain the hydraulic integrity of the dump system. Sourced directly from Multiquip, the 18064SK ensures a correct, hassle-free service without the guesswork of matching individual seal dimensions.

Key Features

• Genuine OEM Seal Materials — Factory-spec seal compounds engineered to hold up against the hydraulic fluid pressure and cycling demands of the dump valve system.
• Complete Kit Format — Includes all seals needed for a full dump valve rebuild in a single part number, so the job gets done in one order.
• Broad Whiteman Buggy Fitment — Compatible with WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, and WTB-16 models.
• Hydraulic System Integrity — Worn or degraded dump valve seals cause fluid bypass and loss of dump control; this kit restores full, responsive bed operation.
• Correct Sealing Geometry — OEM dimensions mean the seals seat properly in the valve body without trimming, shimming, or adaptation.

The dump valve on a hydraulic power buggy controls the release of hydraulic pressure that tips and lowers the buggy's load bed. The seals within this valve prevent internal fluid bypass, ensuring the bed lifts fully and holds position under load. When these seals wear or crack, the valve loses the ability to hold pressure, resulting in sluggish or uncontrolled dumping — a safety concern on any active pour site. Replacing the seals with the correct OEM kit restores consistent, predictable dump performance and protects the broader hydraulic system from contamination and pressure loss.
