Reviews
Finding the right tubing to connect my scent machine to the central air vent used to be a hassle. I ordered the 8*5mm size, and it fits snugly with no fragrance leaks at all. The material feels heavy-duty and doesn't degrade from the aroma oils. If you are doing an HVAC scent setup, just pick your size and go for it!
