This triple-lipped trailer oil seal fits #42 trailer spindles with a seal surface diameter of 2.250 inches, commonly seen on 6 lug or 8 lug oil-lubricated hubs. This oil seal will typically be used on trailer hubs with a 1 3/4 inch x 1 1/4 inch tapered spindle bearing combination, but you can check the specific oil seal size on your current hub to make sure you are purchasing the correct seal. The oil seal will help keep all of the oil contained inside of your hub and keep your bearings fully lubricated and operating safely. The oil seal has an outer diameter of 3.376 inches and will fit a variety of different hubs that are used on trailer axles from 5,200 to 8,000-pound weight capacity. It is important to keep your oil seals in good working condition, as they will prevent water, dust, or other intrusive materials from contaminating your hubs' lubrication, so make sure you are getting a fresh replacement if your current seals seem compromised in any way!
