Product review (5 stars): know how to use the push in connections.
Item fit and worked fine. Only problem was my confusion with the different type fittings for the tubing connections. New valve has push in and it seals and grips the tubing. Old valve had threaded connectors. Checked on line and found instructions to cut off tips of tubes, mark 11/16 inch  and push tube into hole. It grips, no leaks, valve operates and I have ice and water dispenser working. To remove tubing from the push in connection, use small open end wrench, press on the white collar toward valve while pulling on tube.
