This kit comes with 2 gooseneck and 2 pump caps that will fit any tool. The small NU68 fits over the gooseneck,filler tip and the long gooseneck tip to prevent the compound from drying out.Very simple and yet very effective. It is a flexable vinyl material that stays soft and easy to clean up with water. You can use it over and over.
The pump cap NU70 is the same idea. It fits over the end of any hand pump to keep the compound moist and not drying out. Just slip it on, easy to clean and use it over and over made of vinyl and stays flexable.
