Multiquip 18257M Filter to Dump Valve Hose

The Multiquip 18257M Filter to Dump Valve Hose is a genuine OEM hydraulic hose designed for Whiteman hydraulic power buggies in the WBH-16 and WBH-21 series. As a direct OEM replacement, this hose meets the original engineering specifications for material, bore diameter, and end connections — ensuring correct hydraulic fluid flow between the filter and dump valve without adaptation or modification. It is confirmed to fit WBH21EPA, WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, and WBH-21EF models.

Key Features

• Genuine OEM Hydraulic-Grade Construction — Built to the same pressure rating and hose specification as the original, maintaining correct flow between the hydraulic filter and dump valve under load.
• Direct Drop-In Replacement — End fittings and hose length match the original routing on WBH-16 and WBH-21 series buggies, so installation follows the factory hose path without rerouting.
• Broad WBH Series Fitment — Compatible with WBH21EPA, WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, and WBH-21EF power buggies.
• Dump Circuit Integrity — A correctly functioning hose maintains consistent hydraulic pressure to the dump valve, enabling smooth, controlled tipping of the buggy's hopper under full load.
• Hydraulic Safety Compliance — A deteriorated or leaking hose in the dump circuit can cause uncontrolled hopper movement; replacing with a genuine OEM hose restores safe, predictable dump valve operation.

The Filter to Dump Valve Hose carries pressurized hydraulic fluid from the system filter to the dump valve that controls the hopper tipping function on Whiteman hydraulic power buggies. It plays a direct role in the dump circuit — if the hose cracks, collapses internally, or develops a leak, hydraulic pressure to the dump valve drops, resulting in sluggish, erratic, or uncontrolled hopper operation. Replacing a worn hose with the correct OEM part restores full dump circuit performance and keeps the machine operating safely on site.
