Griffin Swivel with Silicone Tubing

Griffin Glass Tools - Swivel with Silicone Tubing. Set Includes: 1 mouthpiece, 1 swivel, and 1 6ft length of silicone hose. This 1/4″blow hose is made entirely of Stainless Steel. This material spins freely and easily and won’t bind up and build corrosion like brass swivels! The inside dimensions are as large as possible in order to avoid blockage from saliva. Both sides of the swivel spin for most free movement possible. The hose is 5/16″outside diameter and will fit snugly inside 12.7 heavy wall tubing.
