The Plenty Silicone Tubing Section Set includes all the necessary silicone tubes to ensure the vapor produced is pure and untainted. Damaged or dirty silicone tubes can lead to contaminants entering the vapor, hence replacing them can enhance the vaporizer’s experience. By doing so, fewer vapors will escape the device, and the aroma will improve. It’s recommended to replace the tubing with fresh ones even if they only show minor stains or cracks as they can still cause vapor contamination.
