Guardian® HP Hub Seal

The Guardian® HP incorporates the best features for preventing the leading causes of seal-life degradation – contamination ingress and heat generation.

Guardian HP Wheel Seal


With its high-performance HNBR-PTFE sealing lip and superior contamination exclusion, Guardian HP has been developed for extra protection and greater sealing. The rubber outer diameter allows for faster hub cleaning with less corrosion damage to the hub.

Installation directly on the axle, rather than the hub bore, guarantees positive alignment every time. No tool impact on the seal means no damage or installation-related failures. Plus, Guardian HP is easy to remove and service, so there’s no opportunity for bearing damage during seal removal.

With over 25 years of proven success, Guardian HP is the OEM seal of choice in the heavy-duty trailer industry. The enhanced seal features offer improved cost-per-mile performance in addition to simple, one-step axle installation.
