Dust caps for Unbraked Hubs
FAQs
What are dust caps for unbraked hubs and why are they needed?
Dust caps are protective covers that fit over the grease ports of unbraked hub assemblies. They keep dirt, moisture and debris out of the hub bearings, helping to maintain lubrication and extend the life of the hub.
Which types of vehicles use dust caps for unbraked hubs?
Dust caps are fitted to the hubs on all trailers.
What material are dust caps made from?
Most dust caps are manufactured from metal or high‑density polyethylene (HDPE) or reinforced nylon, providing resistance to UV, chemicals and impact while remaining lightweight.
How often should dust caps be inspected or replaced?
Inspect dust caps at each routine service interval. Replace them if they show cracks, deformation, or if the sealing surface is damaged, typically every 2‑3 years depending on operating conditions.
