Bearing Buddy stainless steel wheel bearing protector kit — Model 2717 with 23Bra sleeve, self-venting 3 psi pressure regulator

Bearing Buddy Model 2717 is a stainless steel, self-venting wheel bearing protector kit that keeps grease in and water and dirt out of trailer hubs, paired with a 23Bra grease-repellent wheel cover for extra protection.

If you tow a boat, camper, or utility trailer, the hub area is constantly exposed to moisture, road grime, and contaminants that shorten bearing life. The Bearing Buddy 2717 uses a spring-loaded piston and an automatic 3 psi pressure regulator to maintain correct hub pressure, while the included 23Bra sleeve shields grease from external dirt and prevents wheel surface contamination. Combined, they reduce the risk of seal damage and make routine hub maintenance easier and cleaner.

How does the Model 2717 prevent water and dirt from entering my hubs?

The 2717 installs over your dust cap to create a controlled pressure barrier inside the hub. Its piston design maintains positive pressure that resists water intrusion, while the stainless steel construction withstands wet environments without corroding.

• Spring-loaded piston maintains steady 3 psi inside hub
• Positive pressure repels water and road grime
• Stainless steel shell resists freshwater corrosion

What does the automatic pressure relief valve do and why is it useful?

The built-in valve opens if internal pressure rises above the safe threshold, preventing over-pressurization that can push grease past seals or deform components. It keeps hub lubricant where it belongs while avoiding seal damage from excess pressure during temperature changes or over-packing.

• Self-regulates to about 3 psi to avoid overfill issues
• Releases excess grease safely to protect seals
• Works automatically—no manual adjustments required

How easy is installation and what tools do I need?

Installation is straightforward: measure the inside diameter of your hub or the outside of the dust cap for a correct fit, then press the Bearing Buddy into place using a wood block and hammer. No specialized tools or advanced mechanical skills are necessary.

• Measure hub or dust cap for correct model fit
• Tap into place with a wood block and hammer
• No special tools or advanced mechanics required

Why include the 23Bra sleeve and what does it add?

The 23Bra is a protective sleeve that slips over your wheel area to keep grease contained and reduce grime buildup on rims. It prevents grease splatter during operation and adds a second layer of defense against road dirt, simplifying cleanup and preserving wheel appearance.

• Blocks grease from contacting wheel surfaces
• Helps keep rims and lug areas cleaner between services
• Easy to fit and remove for greasing service

Who is this product for? The Bearing Buddy Model 2717 with 23Bra is intended for trailer owners who want dependable hub protection—particularly boat trailer owners and anyone operating in wet or corrosive conditions. It suits DIYers and fleet operators seeking a simple, durable upgrade to extend bearing life, reduce maintenance mess, and protect hub seals. Made from stainless steel and backed by a Lifetime Warranty, it’s a practical choice for freshwater environments where corrosion resistance and automatic pressure control matter.
