Product review (4 stars): Looked around and decided this was the place to purchase
First of all, this item is for a GE side by side refrigerator with a water and ice dispenser in the door.  It may very well fit other brands as well. I must say first of all, the part is the exact same GE factory part that came in a sealed GE factory box identical to the old one down to the length of the tubing which was the perfect length and required no cutting. Not some knock-off from china.  The box was inside of a nicely packed larger shipping box. This part shows available on many other internet appliance parts sites, but most do not indicate whether it actually is GE oem parts or some cheap knockoff with possibly the wrong size tubes. One of the reasons I wrote this is because the description here on Amazon says very little and really only mentions the part number.

 This is the water tank that is located on the inside of the refrigerator on the back wall behind the produce draw. The small tank allows the water a chance to cool down before it is dispensed through the door. The tank is fastened to the back wall with two philips head screws. Two polyethelene tubes come fixed on the tank.  The shorter is the tank entry tube which litterally slide fits snug (without the need of any tools) into the soleniod valve at the back of the refrigerator.  The longer exit tube goes underneath the refrig to the front slide fitting below the door with the water and ice dispenser.  The reason I replaced this part is that the polyethelene tubing had developed tiny cracks that allow very subtle water leak and allowed air into the tubing.  The cracks developed in two seperate areas where the tubing had bends in it. First I began to notice that the water dispenser had a slight water dispensing delay.  At first I though it maybe a failing water valve soleniod. Low and behold the culprit was the fine cracks in the bends of the tubing at the back near the solenoid valve.

It took me about 40 minutes to remove the old tank and tubing and install and run the new tubes in the exact same manner. After it was installed, I thoroughly tested the dispenser to make sure there were no leaks at the tube fittings. Remember to always unplug the electrical cord when inspecting the water features of the refrigerator.  Good luck.
