CAETOUNG 4Pack 2.72'' Trailer Hub Cap - Dust Cap for EZ Lube 7000-8000 lb Axles

Overview

Protect your trailer’s bearings with CAETOUNG’s 4Pack 2.72'' trailer hub cap set. Built for durability, these dust caps feature a carbon steel core with a zinc-plated finish that stands up to road grime, moisture, and the elements. The result is a rugged, corrosion-resistant shield designed for long-term use on demanding trailers in varied conditions.

Premium materials and thoughtful design

The outer shell blends strength with a smooth, low-friction surface, helping resist wear from routine maintenance and weather exposure. The accompanying rubber plugs are soft to the touch yet resilient against water, oils, and chemicals, delivering a reliable seal when you need it most.

Why this matters

Keeping dust, dirt, and moisture out of wheel bearings helps preserve grease effectiveness and reduce the risk of contamination. With an outer diameter of 2.72 inches, these caps fit most standard hubs in the 7000–8000 lb range and are compatible with EZ Lube and standard axles, offering flexible application for many trailers.
