8K Valcrum Cap for Oil Bath Hubs | Trailer Hub Oil/Grease Cap
$69.95
Trailer hubs rely on proper lubrication to protect bearings and other internal components from heat, friction, and wear. The 8K Valcrum Cap for Oil Bath Hubs is a threaded aluminum replacement cap engineered to seal and service the lubrication of 8,000 lb trailer axle hubs — whether your trailer uses an oil bath or grease lubrication system.
This Valcrum cap replaces standard plastic caps with a more durable and service-friendly solution. The magnetic vent plug attracts metal particles that naturally occur during use, helping you identify early wear and prevent bearing failure. The clear viewing lens allows you to check lubricant levels at a glance, and the convenient side fill and drain accessmeans you can service your hubs without removing the entire cap.
Whether you’re upgrading your maintenance routine or replacing a worn cap, this aluminum hub cap helps protect your trailer’s hubs from water, road debris, and corrosion — extending the life of your bearings and lubrication system.
