This is a Vanishing Hearts design driptip. It will fit in 510 size holes in most RDAs and RTAs
It is designed to increase flavor of your favorite ejuice as well as lessen the soundbox effect (the 'pop' sound generated by heated ejuice) by creating a cyclone airflow effect as well as widening the tunnel towards the tip.
Photo shown is 3D printed in 'matte gold steel' version.
We recommend using this driptip on RTAs rather than RDAs as it (when printed in silver) can heat up quickly.
We have tested on several RTAs including Zephyrus, Atlantis, Subtank etc. successfully without it overheating.
O-rings for the drip is not included. We have tested 1.5 x 8 x 8mm O-rings from Fasttech.com. Link below.
