Silicon tube in 8 differente sizes. It has a very high flexibility, so it dosn't extend and the line doesn't cut it through. It fixes the float slide-free for a long time. Because of its high flexibility one size can be used for more sizes of floats.We recommend to reach the suitable press effect, the fixed part should be 1 mm bigger than the nominal size of the tube. E.g. a tube of 7mm should be used to a carbon, steel or glass fibre stem of 8 mm.
