The Kanger Pangu PGOCC Replacement Coil structure runs the entire length of the tank and is sleeved by the included drip tip. Removing the drip tip allows users to twist the coil itself to adjust wicking port exposure, making adjustment simple and easy. The full chamber coil design allows for a direct to user airflow experience, with a full 8mm bore from coil to tip, removing any airflow obstructions.
