Don't use 5mm ID X 10mm OD silicone tubing with Caskwidge floats in a corny keg. Too rigid for narrow cornies therefore prone to getting jammed on the keg wall then sucking CO2. 6 to 6.5mm ID with a 1 to 1.5mm wall is more reliable. The tubing supplied by Caskwidge (roughly 5mm ID X 10mm OD) is designed for casks, which are much wider than corny kegs
