Frequently Asked Questions

Q: What size hub is this trailer dust cap compatible with?

A: These galvanized steel trailer hub dust caps are designed for hubs with a center diameter of 48mm (approximately 1.89 inches). They are specifically made as a replacement for Alko trailer wheel hubs — non-European brake drum version. Always measure your hub opening before ordering to confirm compatibility.

Q: Do I need special tools to install these 48mm dust caps?

A: No special tools are required. The dust caps are designed for straightforward installation — simply align the cap with the hub opening and press or gently tap it into place. Most users can complete installation in just a few minutes without professional assistance.

Q: Why is a galvanized steel dust cap better than a plain steel or plastic one?

A: Galvanized steel offers a significant advantage over plain steel or plastic alternatives. The zinc galvanizing process creates a corrosion-resistant barrier that protects against road salt, moisture, and debris. This means your trailer hub dust cap will maintain its protective seal and structural integrity far longer, reducing the need for frequent replacements.

Q: How many dust caps are included in this order?

A: Each order includes 2 x 48mm Trailer Hub Dust Caps, making this pack ideal for replacing both hubs on a single-axle trailer in one purchase.
