Dexter Axle Engine Oil Dust Cap
Clean oil flow depends on keeping contaminants out of the access points, and the Dexter Axle Engine Oil Dust Cap closes off that vulnerability with a good fit. This 4-inch OD plastic cap is matched to Dexter axle hubs, where its fit contributes to oil bath seal longevity and limits outer hub exposure. Often replaced during inspections or seal service, this cap helps isolate oil from dirt, moisture, or mechanical damage. Especially relevant in trailers and light-duty commercial trucks, the Dexter Axle 21-36 is a maintenance staple that does its job without attracting notice.
