2t Australian grommet dust caps fit the following Hubs and bearing sets;

  • Parallel
  • Two Tonne

Some hubs do not have machined chamfers in the boss and rear of the wheel hub. Insertion can be difficult. Using a pipe of the correct diameter significantly improves the ease of installation.

Dust cap can become lose if hammered into position too frequently even on the first insert. Once the dust cap is home, stop hitting it. The extra hit can make it loose-fitting.

Question: Should I fill my grease cap full of grease.
Answer: No, the purpose of the grease cap is to catch excess grease from the bearing cavity. Your grease cap should be inserted dry.

Grease is generally in oversupply during the greasing process. Grease will exit the bearing cavity at high speeds and during the initial heating and cooling process. Note: Grease never re-enters the bearing cavity one caught in the grease cap.

What is the purpose of the grease cap?

  • To catch grease?
  • Or to prevent the ingress of dust?

But what exactly are grease caps used? Are they simply a decorative accessory for your trailer, or do they serve a real purpose? Well, you can be assured that grease caps are not decorative.

Although a shiny chrome grease cap can be a nice touch on a rather dull looking trailer wheel, they serve a fundamental purpose. Grease caps are the small, round, metal covers you see at the very centre of a wheel hub. Sometimes they’re called dust caps, but for clarity, we’ll call them grease caps from this point forward.

Grease caps protect your wheel bearings from the dirt, dust, sand, water, salt and road grime that can (and will) destroy bearings. Without grease caps, your wheel bearings wouldn’t survive for very long out on the road.
