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. 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.
