The tubing connectors were unfamiliar to me, and I tried to pry out the tubing connector instead of researching the proper method. These connectors turned out to be very simple to remove. Simply hold the insert against the device while pulling the tube out. The new tube was installed in about 3 minutes by just pushing it into the valve port, and connecting the other end to the standard hose fitting on the water supply .
The part ordered was an exact fit for my Jenn-Air under counter ice machine. Thanks
