Keep road grime, moisture, and debris out of your wheel bearings with Lippert's factory-spec dust caps. These direct-replacement caps are engineered to fit standard 5,200 to 6,000 lb trailer axles with a 2.5-inch bore hub -- the size commonly found on single and tandem axle RV trailers, fifth-wheels, and travel trailers in that weight class. Buying 10 at a time means you have spares on hand for a full multi-axle rig plus extras for the road kit.
Wheel bearing failure is one of the most preventable -- and most expensive -- roadside emergencies an RV owner faces. A properly seated dust cap is the first line of defense, sealing out water, road salt, sand, and highway debris that cause premature bearing wear. Lippert's 693795 dust caps are formed to the correct press-fit diameter for 2.5-inch bore hubs and maintain a secure, rattle-free seal mile after mile.
These caps match OEM specifications used across Lippert-branded and Lippert-supplied axle assemblies, making them a reliable like-for-like replacement when caps are damaged during routine bearing service, tire changes, or inspections.
2.5-inch bore diameter press-fits securely into standard 5,200-6,000 lb rated hubs without modification or adapters.
Ten caps per pack -- enough to service a full tandem or triple-axle trailer with spares left for your maintenance kit.

Dust caps on trailer hubs should be inspected at every bearing repack interval -- typically every 10,000 to 12,000 miles or annually, whichever comes first. Replacement is straightforward:
