Multiquip 18020 Hose, Dump Valve to Hydraulic Piston

The Multiquip 18020 is a genuine OEM Dump Valve to Hydraulic Piston Hose designed for Whiteman hydraulic power buggy models including the WBH-16, WBH-16E, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, and WBH21EPA series. Sourced directly from Multiquip, this hose carries the exact pressure ratings, end fittings, and routing dimensions of the original component — no trimming or adapting required. Confirming part number 18020 against your serial plate before ordering is the fastest way to ensure a correct match across the WBH buggy lineup.

Key Features

• Genuine OEM Hydraulic-Grade Construction — Built to the same pressure tolerance and burst rating as the original hose, maintaining full hydraulic system integrity in the dump circuit.
• Direct-Fit End Connections — Hose terminates with OEM-matched fittings that connect directly to the dump valve and hydraulic piston ports without thread adapters or re-flaring.
• Broad WBH Series Coverage — Compatible with WBH-16, WBH-16E, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, and WBH21EPA Whiteman power buggies.
• Consistent Dump Cycle Performance — A sound hose delivers full hydraulic pressure to the piston on every dump cycle; a cracked or swollen hose causes sluggish or incomplete bed actuation under load.
• Hydraulic Leak Prevention — Replacing a failing hose before it ruptures protects surrounding hydraulic components, the frame, and the operator from pressurized fluid exposure.

The dump valve to hydraulic piston hose is the pressurized fluid line that transmits hydraulic force from the dump valve to the piston that raises and tilts the buggy's material tub. When the operator activates the dump, the valve opens and directs fluid through this hose to extend the piston and tip the load. Over time, the hose can stiffen, crack at the fittings, or develop internal degradation that restricts flow — leading to a slow, weak, or unresponsive dump cycle. Replacing a worn hose with a correct OEM unit restores full piston travel and ensures the dump mechanism operates predictably and safely on every cycle.
