The Multiquip 491213 is a genuine OEM Hydraulic Oil Tank Plug 3/4"-14 NPT designed for WBH16 and WBH21 series Whiteman hydraulic power buggies. As a direct OEM replacement, this plug is manufactured to the exact thread specification and material standard required by the original equipment, ensuring a secure, leak-free seal on the hydraulic oil tank. It is confirmed compatible with a wide range of WBH models including the WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH21EPA, WBH-21EF, and WBH-21EFP. Sourced directly from Multiquip, part 491213 gives you confidence that you are installing the correct component the first time.
Key Features
- Genuine OEM Thread Specification — Machined to the correct 3/4"-14 NPT thread standard, ensuring proper engagement and a pressure-tight seal on the hydraulic oil tank port.
- Drop-In Compatibility — Threads directly into the existing tank port on WBH16 and WBH21 series buggies with no rework or modification to the tank fitting.
- Broad WBH Series Fitment — Covers multiple WBH configurations including AWD, foam-filled tire, and electric-start variants across the WBH-16 and WBH-21 families.
- Hydraulic System Integrity — A properly sealed tank plug prevents hydraulic fluid loss and contamination, maintaining consistent hydraulic pressure for smooth buggy drive and steering response.
- Fluid Containment Safety — A failed or missing oil tank plug can result in hydraulic fluid leaks that create slip hazards on the jobsite; replacing with the correct OEM plug eliminates this risk.
The hydraulic oil tank plug seals the fill or drain port on the buggy's hydraulic fluid reservoir, keeping the hydraulic oil contained and the system free from dirt and moisture ingress. On WBH series power buggies, the hydraulic system drives the wheel motors and controls travel speed and direction, so maintaining a sealed, properly filled reservoir is critical to consistent machine performance. A damaged, cross-threaded, or missing plug can cause fluid loss, air entry into the hydraulic circuit, and ultimately loss of drive power or erratic machine behavior.
