Duh, oil, and seal, what do you think those 2 words in that combination would possibly mean? In your application of these 2 words, would ';seal'; possible mean an open drain for oil? How about a fitting that oil flows through. Still not right, gee wiz, what could it possibly mean, oil and seal used together? I know, it's something used to let oil out. Why on earth would anyone want to keep oil in an engine, or a transmission?


Oil seal, it is a cork, or rubber device of some kind that is used between to mating surfaces to keep oil in the engine. I guess that you might be clueless about engines in general. Yes, there are many industrial applications for seals of many different applications. Even the plumbing in your house uses seals to keep water from getting out of them where it would not be convenient to have the water leave the pipe. There is a seal, although it is composed of wax, that seals the toilet to the drain pipe it sits on top of to keep water and human waste from getting out and covering the floor.
