This Captive Cap comes with an engraved Palm Island design to celebrate summer vibes! DynaVap’s signature Cap is engineered to “click” when heated to the correct and optimal vaping temperature. The Captive Cap is made of medical grade stainless steel and makes all DynaVap dry herb vaporizers work. This version of the Cap is updated from the original Cap and has two indentations on the sides to help the Cap stay on your Tip. These indentations allow for a more even distribution of airflow and for the free movement or spin of the Cap on your DynaVap vaporizer. The Cap is what makes a DynaVap device a vaporizer and will fit with any DynaVap Tip. THE CAPTIVE CAP FEATURES Temperature indicating “click” Indentations to keep your Cap on the Tip Easier heating with Cap movement/spinning capabilities Digger-outer tool Durably made with stainless steel Note: Sometimes the Cap will click twice. This is completely normal. If your new cap is loose, give it a gentle squeeze to adjust the fit.
