Premium Aluminum Silicone Hose Kit helped create new visuals for smokers and added a new element of creativity within hookah. The smooth exterior is crafted from aircraft grade aluminum. The tubing is crafted from a medical grade silicone like many other washable hoses, but the silicone goes through a beneficial platinum curing process. The high quality silicone fights flavors from latching onto the interior tubing, and with a quick rinse using water the hose is like new again. Using a hose as flexible as this one can cause pinches in airflow because of its elasticity hence it comes with a anti-kink spring. This spring can be removed if not needed.
