Pac-Seal Shaft Seal Kit 22745 New This item was purchased from a large business inventory reduction sale. I do not know the history of it. Many of the items from this purchase turned out to be new items that were kept as spares. The box has shelf wear and the label is gone, but the kit is new. The part number is hand written on the box. The OD of the rubber seal ring is about 2 1/8". I do not know the age of this kit, but the rubber seems to be pliable and in good condition at this time. I am not able to test it. It only comes with what is shown in the pictures. S550-18 d
