Should try the Maze1C.. I swear that thing wasn't designed to be used with 1/2" hose, and there's no way in hell you can use a hose clamp AND their clip.. Ahh well.. You know, someone was telling me the other day that using 5/8" barbs with 1/2" ID silicone hose works GREAT. It's fairly easy to force the flexible silicone hose over the larger barbs, and with it stretched like that, it doesn't leak a drop. You also get less restriction at the barbs with 5/8" barbs..
