The Fulton Trailer Bearing Protector's are designed to fit your standard 1.98 inch Galvanized or Painted Steel Boat Trailer Hubs. These Bearing Protectors feature a grease fitting on the end so you can add grease to the 4 lug or 5 lug hubs. Doing so will build up pressure in the hub and will actively dispel water and debris, keeping the inside of your Hub and your Trailer Hub Grease clear of contaminants. With the Built-in pressure relief, you can rest assured that you won't be blowing out the rear seal. Grease will come out the front of the bearing protector to indicate that the hub is full, and that no more grease/pressure should be added to the hub.
