Product Description
KAIXINM 2pcs 1.98in Protectors, Stainless Steel Trailer Bearing Lubricators with Spring - Loaded Piston, Universal Fit for Boat and Trailer Hubs
- Spring-Loaded Pressure Seal: These protectors use a spring-loaded piston to maintain a constant 3psi pressure on the grease inside your trailer or boat hub, creating a barrier that keeps water, dust, and debris from entering and damaging your bearings during use.
- Automatic Pressure Relief: The built-in automatic pressure relief feature in each prevents over-filling and dangerous over-pressurization when using a grease gun, ensuring safe and reliable operation without risking seal blowout or hub damage.
- Universal Application: Designed for universal fit on standard 1.98in hub bores, these stainless steel lubricators work perfectly on boat trailers, utility trailers, RVs, and other axle-based vehicles, making them ideal for marine, recreational, and commercial users alike.
- - Stainless Steel: Made from high-grade stainless steel, these protectors resist rust and even in harsh marine environments, offering long-lasting protection and maintaining smooth performance season after season without degradation.
- Easy Installation and Monitoring: Installing these units is quick and mess-free—just thread them onto your hub, fill with a standard grease gun, and monitor grease levels anytime by removing the cap, saving you time and preventing costly bearing failures.
