Protect your wheel bearings from dirt, moisture, and premature wear with this grease cap designed for hub sizes 440, 540, and 545. This cup-shaped metal expansion plug — also known as a dust cap or bearing protector — press-fits into the hub opening of a trailer or vehicle wheel to seal the bearing cavity and keep grease in while keeping contaminants out. The galvanized steel construction with a dull silver finish provides corrosion resistance in both road and marine environments, standing up to salt spray and wash-downs.
Product Facts:
- Single metal grease cap (dust cap/freeze plug/core plug) with cup-shaped design
- Galvanized steel construction with dull metallic silver/grey finish
- Flanged edge for installation guidance
- Size fits hub applications 440, 540, and 545
- Estimated 20-60mm diameter range
Perfect for:
- The flanged rim guides the cap into place during installation, and the rigid construction holds securely under normal operating conditions without backing out
- Properly sealed bearings run cooler and last longer, reducing the frequency of repacking and replacement
This is an essential maintenance part for trailer owners, mechanics, and DIYers servicing boat trailers, utility trailers, or equipment hubs.
