Key Features
- OEM-Grade Sealing Material — Manufactured to Multiquip's original material specification, delivering the thread engagement and compression needed to maintain a leak-free hydraulic oil tank seal under operating pressure.
- Direct-Thread Installation — Sized at 1/2" to thread directly into the hydraulic oil tank port with no adapters or modifications to the tank fitting.
- Broad Model Coverage — Fits WBH-16, WBH-16E, WBH-16EAWD, WPB16, WPB16E power buggies, and the VR-36HA vibratory roller, covering a wide range of Multiquip hydraulic equipment.
- Hydraulic System Integrity — A correctly seated plug prevents oil loss and contamination ingress, keeping the hydraulic system at proper fluid level and protecting pumps, valves, and actuators from premature wear.
- Genuine OEM Part — Part number this part is sourced directly from Multiquip, ensuring it matches the original component exactly in thread specification, form, and function.
The hydraulic oil tank plug seals the fill or drain port on the hydraulic reservoir, preventing fluid from leaking out and blocking airborne contaminants from entering the system. On equipment like power buggies and vibratory rollers, the hydraulic system powers drive and control functions, so maintaining proper fluid containment is critical to consistent machine performance. A damaged, missing, or incorrect plug can lead to fluid loss, system pressure drop, and accelerated wear on hydraulic components throughout the machine.
