Suction tube 14.5mm for Bubbler
I have 2 main whips that I use for one being this and the other being the Rogue Wax Works tubing with their acrylic mouthpiece. This one has huge airflow so it can cool down your diffuser pretty quick if you just start suckin on it. That being said it does seem to produce much cooler vapor than the more narrow tube and the length just means I can put my piece further back on my desk so A+ in my book.
It was a perfect replacement
