Read about the loctite fix here also. Did not know I had removable valves until I got a flat and had to inflate my tire three (3) Times. First time one of the o-rings came loose unseated in the hose. Second time the valve came out and used my co2 for the third time. Did not get to full inflation but I did not want to risk doing it a forth time and only had one co2 with me. Got home and did the loctite red on all the tubes.
