How to use it?
Just pop your 1/4"tube onto each end and push until it won't go in. To remove it, just push in the outer ring on each end and pull it out. You need to make sure the tubing is cut square to make sure there are no leaks. Make sure you cut the tubing even and straight with no crimping it. Then insert it straight in and all the way into the connector. If it is bent, or not inserted all the way in, or curled, it may leak.
