Riptide is One of the newest Subtanks in the market. The Riptide tank is a BVC coil tank that can be used with either 0.3O or 0.5 O coil heads. The interior organic cotton that surrounds the coil is covered by TURBO-FLOW technology that incorporates a nickel mesh that turbo-wicks the liquid to the coil to prevent dry hits and improve the liquid and flavor delivery. The Riptide also incorporates dual cyclops style airflow with adjustment stub so that you don’t keep spinning your airflow control while trying to replace your coil. Also includes adjustable 510 pin and 4ml capacity Pyrex glass tank. The Riptide sub tank is compatible with Triton and Atlantis coils.
