This is a DNA design driptip heatsink in stainless steel material. It will fit in 510 size holes in most RDAs and RTAs
* Photo shown is 3D printed in 'Raw Bronze' version.
We recommend using this item 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 is not included. We have tested 1.5 x 8 x 8mm O-rings from Fasttech.com. Link below.
