From the standard connector that won't hold anything, to those that won't come loose. They are good until you have to pull the tube, and then all efforts will not go far. Those things just didn't come out. I had to cut and unscrew the pipe. Replaced them with two others in the package and encountered the same problem. Could it be the Capricorn tube? I can't say for sure as I haven't tried them with anything else.
