VALCRUM 9K-10KGD OIL HUB CAP, HYDRO-SHIELD (DEXTER)

A 9K–10K GD Oil Hub Cap, Hydro-Shield (Dexter) is a protective cap used on Dexter trailer axles with oil-lubricated wheel hubs.

Function

• Retains the hub oil: Seals the wheel hub to keep the lubricating oil inside the hub cavity.
• Protects the bearings: Helps maintain proper lubrication of the wheel bearings, reducing friction, heat, and wear.
• Prevents contamination: Keeps water, dirt, dust, and other contaminants from entering the hub and damaging the bearings.
• Provides a visual inspection point: The cap typically allows the hub oil level and condition to be checked without removing the hub.
• Hydro-Shield protection: The Hydro-Shield design provides additional protection against water intrusion, particularly in wet or submerged operating conditions.
• Maintains hub integrity: Helps preserve the sealed, oil-bath lubrication system used on the axle.
