The Multiquip 513594 is a genuine OEM Adapter Plug designed for Whiteman hydraulic power buggy models including the WBH21EPA, WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-21EFP, WBH-16EAWD, and WBH-16EAWDF series. As a factory-sourced component, it is manufactured to the same specifications as the original part installed at the time of production, ensuring a direct, accurate fit within the hydraulic system. If you are servicing any of the listed WBH-series buggies, part number 513594 is the correct replacement to restore full system integrity.

Key Features

• Genuine OEM Construction — Sourced directly from Multiquip, this adapter plug is manufactured to the same material and dimensional tolerances as the original, maintaining hydraulic system sealing performance throughout the connection point.
• Direct-Fit Replacement — Engineered to thread and seat exactly as the factory-installed plug, eliminating the guesswork of sourcing a cross-reference part for WBH-series hydraulic buggies.
• Broad WBH-Series Compatibility — Confirmed fitment across WBH21EPA, WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-21EFP, WBH-16EAWD, and WBH-16EAWDF models.
• Leak-Free Hydraulic Integrity — A correctly seated adapter plug maintains pressure within the hydraulic circuit; a worn or damaged plug can cause fluid loss, pressure drop, and loss of drive or lift function on the buggy.
• Verified by Part Number — Ordering by Multiquip part number 513594 confirms you are receiving the exact component specified for these machines, not a generic substitute.

An adapter plug serves as a threaded fitting within the hydraulic circuit of the power buggy, creating a sealed transition point between hydraulic lines, ports, or components. It prevents fluid from escaping the system while maintaining the pressure required for the buggy's hydraulic functions — such as dumping or drive operation — to perform correctly. When this plug becomes damaged, corroded, or develops a leak, hydraulic pressure drops, which can cause sluggish or non-responsive machine behavior and potential fluid contamination of the work area.
