The Uriah E-Z Lube Rubber Trailer Hub Grease Cap Plug is a vital replacement component designed to seal the access hole on E-Z Lube style trailer axle dust caps. You will find that this high quality rubber plug provides a tight, friction-fit seal that prevents road grime, dust, and moisture from contaminating your wheel bearings. It feels flexible yet durable, allowing you to easily pop it off with your thumb or a flathead screwdriver when it is time to apply fresh grease to the zerk fitting inside the spindle. Because these plugs can become brittle or go missing over time, keeping your hubs sealed with a fresh set is a simple and effective way to prevent premature bearing failure and expensive axle repairs.

To ensure the best possible seal, you should wipe the inner rim of the metal dust cap with a clean rag to remove any old grease or grit before inserting the new plug. You should press firmly around the entire edge of the plug until you feel it seat fully into the opening to prevent it from vibrating loose on the highway. If you notice your current plugs are starting to show small cracks or have become hard to the touch, it is time to replace them before they allow moisture to reach your bearings. It is always a smart idea to keep a couple of these spare plugs in your trailer’s tool box since they are small and easily lost during roadside maintenance.
