RDA Top Caps
These are combined top caps and drip tips which replace the whole top part of a compatible RDA. They provide a wide bore and are designed to sit flush on top of the tank. They're an awesome alternative to a drip tip and intended for those who like to drip without removing the top, plus you'll be amazed at the clouds you'll get. Available in two sizes, either 22mm or 28.5mm. they're compatible with most RDA's that have a push on top cap such as the Tobh Atty, Stillare, Vulcan, Crest, Plume Veil and Halo.
RDA stands for Rebuildable Dripping Atomiser and they're renowned for their superior performance which can be individually customised to the vapers exact requirements. These tanks are used by experienced, some might say geeky, vapers and cloud chasers.
