Hub Grease Cap, 2.331 Diameter X 1.28 Tall

Hub Cap, 2.333X1.28

The 1601 Drive-In Hub Cap (2.333") is a heavy-duty grease cap designed to protect trailer wheel bearings from dirt, debris, and moisture. Built from heavy-gauge steel with a corrosion-resistant zinc finish, this cap helps keep grease inside the hub while preventing contaminants from entering the bearing assembly. Its press-fit (drive-in) design provides a secure seal and allows for quick installation using a rubber mallet—no special tools required. With a standard 2.333" outer diameter, it is commonly used on trailer axles and agricultural equipment, helping extend bearing life and maintain smooth wheel operation.
