Attwood Marine
Attwood Marine HubMate Wheel Bearing Protectors prevent trailer wheel bearing failures by replacing standard dust caps and maintaining positive grease pressure to keep water, salt spray, and road debris out of your trailer's hub cavities. They feature an integrated, accessible Zerk grease fitting that allows you to easily add marine grease without disassembling the hub.
Key Benefits & Usage Tips
- Submersible Defense: Essential for boat trailers backed directly into fresh or saltwater boat ramps.
- No-Demolition Refills: Hook your grease gun directly onto the integrated fitting to flush or fill the hub effortlessly.
- Overfill Caution: When pumping marine-grade grease, stop immediately when the spring-loaded piston assembly barely begins to move. Over-filling can rupture your trailer's rear inner hub grease seals.
Don't compromise on the safety and efficiency of your trailer. Shop our range of Attwood Marine wheel bearing protectors today and ensure your next boating trip is worry-free!
