This is a Hex Torque design driptip in stainless steel material. 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 'premium silver' version.
When printed in silver or (plated) brass we recommend using this driptip on RTAs rather than RDAs as it 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.
