This Volcano Hybrid tube set consists of 3 tubes, and 3 black mouthpieces. The tubing is one meter long and made of food-safe, heat-resistant silicone that doesn’t attract dust or pet hair. The tube flexer fits on top of the Volcano Hybrid filling chamber and swivels 360° to easily pass it around in groups. If you have lost your original tube kit or if yours become damaged or you want some spares kicking around these are a perfect replacement.
