That could be the correct one, but what I would do is take the bell that slips on the end of the torque tube and the two flat rings at the back of the bell that are inside the hand tightened screw on ring and go to the "O" ring store, find the right size and buy it. According to The Filling Station, the price is $.75. Another thought would be to call The Filling Station and ask there "O" ring will work on your particular drive line.
What ever you do, the point is that IT WILL NOT LEAK with a rubber "O" ring. It's easy enough to either find one locally or call and order one. You have to take the assembly apart either way. I would fix the problem so you don't have a problem anymore.
