Protective Function: Our trailer hub dust caps effectively prevent dust from entering the hub interior, maintaining cleanliness within the axle and avoiding issues like jamming or wear caused by dust accumulation. Simultaneously, the dust cap creates a sealed conditions, shielding grease from external exposure. This ensures the grease maintains stable lubrication properties over time, extending lubrication intervals.
Cover Scratches: Once installed, our trailer hub dust caps conceal minor gaps and slight scratches on the hub edges caused by prolonged use, unifying the appearance of what might otherwise look cluttered. Featuring a lightweight design, they add no extra weight to the trailer and occupy minimal space when stored as spares.
High Quality Material: Our trailer wheel hub dust caps are crafted from high-quality carbon steel. This material offers good hardness and toughness, effectively withstanding daily impacts and friction without deformation or damage. It maintains stable structural integrity and protective performance under any demanding conditions. Carbon steel builds a reliable protective barrier for trailer wheel hubs, significantly extending their service life.

Additionally, it is widely compatible with common 4-lug and 5-lug axles on the market. Whether used on trailer axles with braking systems or non-braking trailer axles serving only as support, installation is straightforward as long as the specifications are met.
Easy Installation: Installing our trailer hub dust caps is straightforward. First, clean any dust or debris from the hub surface to ensure a clean mounting area. Next, align the dust cap with the hub mounting position and gently press it into place. Then, evenly press the edges of the dust cap with your hand to ensure a tight seal with the hub, leaving no gaps. Finally, check that the installation is secure.
