This double-lipped trailer seal fits some UFP hubs and rotors with an inner diameter of 1.68 inches, commonly seen on 5 lug UFP 3,700 lb axles. This is a non-standard trailer seal size, so make sure you are purchasing the correct sized seal for your trailer, if you have a standard 3,500 lb trailer spindle you will generally need a 1.72 inch ID 3500 lb Trailer Grease Seal. This seal has an outer diameter of 2.56 inches, which will fit the seal bore for most 5 lug trailer hubs as well as the 3500 lb UFP 9.75 inch Integral Rotor. This is one of the more common UFP seals, but you will need to double-check the dimensions of the parts that you are replacing to make sure you are getting compatible parts to keep your trailer in safe operating condition. The double-lipped design helps keep grease inside of the hub to keep it well lubricated, and at the same time keep dust, water, and other intrusive materials out.
