FAQs

What does 'internal fit' mean for this dust cap?

An internal fit cap means it slots into the hollow center of the wheel hub assembly, rather than fitting over the outside of the hub. The 72.5mm measurement refers to the size of the opening it fits into.

How do I know if this 72.5mm cap will fit my trailer?

Measure the internal diameter of the hub opening where the dust cap sits. If this measurement is 72.5mm, the cap should fit. This cap is specifically listed for Ifor Williams trailers but verifying your hub size is key.

What is the main benefit of using a dust cap?

The primary benefit is protecting your wheel bearings from dust, grit, water, and other contaminants. This protection prevents premature wear and extends the lifespan of the bearings.

Is this listing for a single hub cap or a set?

This listing is for one single 72.5mm dust cap. You will need to purchase the quantity required for all wheels needing replacement.

What materials is the dust cap made from?

While specific material composition is not detailed, these caps are typically made from durable metal or robust plastic designed to withstand road conditions and protect the bearings.

Can I use this on a non-Ifor Williams trailer?

Yes, if the internal diameter of your trailer's hub opening measures 72.5mm, this cap should be compatible, regardless of the trailer brand.

Troubleshooting

Cap is difficult to install

Ensure the hub opening is clean and free of obstructions. Verify that the hub's internal diameter matches the cap's 72.5mm specification. Apply a small amount of grease to the cap's edge for easier insertion, but do not force it.

Cap rattles or feels loose

The cap may not be fully seated, or the hub's internal diameter might be slightly larger than specified. Re-seat the cap firmly. If the issue persists, consider using a suitable adhesive or sealant for a more permanent fix, or investigate if a larger size cap is required.

Bearing appears contaminated despite cap

Check the dust cap for any cracks or damage that could allow ingress. Also, inspect the hub seal and bearing assembly itself for any failure points. The cap may need replacement or further inspection of the bearing system is required.

Setup, Compatibility & Care
