Perfect Fit for My Dexter Hubs

Snug drive-in fit with no wobble. The rubber plug lines up perfectly with the grease zerk. Keeps dirt out and grease in—exactly what I needed.

Exactly What My Lippert Hubs Needed

Replaced worn originals that let in water. These seal tightly and the rubber plug holds up well. No more bearing washouts after rain.

Solid Build, No Loose Fit

Some cheap caps wobble and vibrate off. Not these—hammered in with a tight seal and haven’t budged, even at highway speeds. Reliable and secure.

Good Protection, But Check Zerk Alignment

Some caps aligned perfectly with the grease fitting; one was slightly off. Rotated it by hand before driving in—fixed the issue. Works great now.

Excellent Value – Buy in Bulk

At $4, it’s cheaper than most local stores. Ordered six and saved time and money. Will keep spares in my trailer toolkit.
