Dexter Marine Products Super Lube Dust Caps with Grommets Pair Bearing Protector

Dexter Marine Products Super Lube Dust Caps with Grommets are trailer wheel bearing protectors, also called grease caps, bearing dust caps or hub caps. They are made for Dexter trailer axles with a grease zerk fitting on the end of the spindle. Each pair covers the hub opening to help keep dirt, dust and moisture out of the bearings. The design also lets you add grease to the bearings without taking the hub apart.

Key Features:

• Super Lube design: Lets you force fresh grease straight into the bearing through the zerk fitting for easier routine maintenance.
• Rubber expansion grommets: The grommet gives the cap a snug seal in the hub.
• Bearing protection: Helps keep grease in and contaminants out, which supports longer bearing life on boat, utility and recreational trailers.
• Replacement-ready: Suited to replacing damaged, cracked or missing dust caps on compatible Super Lube hubs.
• Sold as a pair: Each listing is a pair of dust caps with grommets.

Dexter has made trailer axles and brake components for the utility, marine, RV and specialty trailer markets for decades. Regular greasing and good bearing protection are especially important for marine trailers, which are often exposed to water and road debris. Check your hub style and the cap size listed on each item to confirm it matches before you order.
