- Oil access: Allows the hub to be filled or serviced with the specified lubricant.
- Lubrication: Helps maintain the oil-bath system that lubricates the wheel bearings while the trailer is operating.
- Visual inspection: The cap may also allow the oil level and condition to be checked without removing the hub.
