Hey Kaleb, if you look at the inner portion of the Grease Seal Kit part # DX49CR you can see three lips/ridges. That is what is meant by triple lip. I attached a picture that has the section to look at.

The previous explanation is very good. The photo shows the triple seal and as far has how I fell about the product. Well, it worked as well as any seal I have ever used. I was having a difficult time with the back side of my bearings leaking the oil I use! This triple seal has ended that issue. I give them a 5-star rating, strong recommendation. Give them a try!
