R and P Knowledge Hub

Dust caps are installed on the outer end of trailer hubs to protect wheel bearings and grease from contamination. The cap seals the hub cavity and prevents dirt, water, and road debris from entering the bearing assembly.

EZ-Lube style dust caps include a removable rubber plug that allows grease to be added through the spindle grease fitting without removing the cap. This simplifies routine maintenance on trailers equipped with EZ-Lube axles.

Before ordering, measure the inside diameter of the hub bore where the dust cap installs. The measurement for this cap is 2.44 inches, which is commonly used on 5K, 6K, and 7K trailer hubs.
