AL-KO Grease Cap - 57 mm Galvanised Steel

The AL-KO grease cap is designed to protect your trailer or caravan wheel bearings from water, dust, road grit, and other contaminants, thereby extending their lifespan and maintaining performance.

This 57 mm cap is specifically designed for AL-KO Euro hubs with a hub bore of approximately 55.5 mm. Always measure your hub bore and check compatibility specifications before purchasing.

The cap is constructed from galvanised steel, which offers good resistance to corrosion and durability for outdoor use.

It features a secure push-in fit. Align the cap with the hub bore and push it in firmly until it is seated securely.

No, this cap is specifically designed for AL-KO Euro hubs. Using it on incompatible hubs may result in a poor fit and inadequate protection.

It is recommended to inspect the grease cap during routine trailer maintenance, such as before long journeys or at least annually, to ensure it is securely fitted and free from damage.

If the cap is bent, cracked, or shows significant signs of corrosion that compromise its seal, it should be replaced immediately to prevent contaminants from reaching the wheel bearings.

Ensure the hub bore is clean and free of any obstructions or old sealant. Check that you are using the correct size cap for your AL-KO Euro hub.

The cap may not be fully seated. Remove and re-install, ensuring it is pushed in evenly and completely. If it remains loose, the hub bore or the cap itself may be damaged or worn, requiring replacement.

The galvanised finish provides corrosion resistance, but some surface rust may appear over time. Clean with a damp cloth. Significant pitting or flaking indicates the cap's protective layer is compromised and may need replacement to ensure continued protection of the hub.
