The Captive Cap by DynaVap has been designed to fit all recent DynaVap tips. We also have the Low Temperature Captive Cap available in this listing.
The Captive Cap has a small indent on each side of the cap which makes the cap more secure and stops it sliding off during use or falling off in a pocket. This indent allows the VapCap to be screwed up and down the threading of the Titanium Tip and the Stainless Steel Tip (2020) using the airflow threading or Tip indents respectively. Removing the Captive Cap using this slight unscrewing motion means you will also not accidentally pull the Tip from your stem when removing the VapCap.
Another change which has been made to the Captive Cap over the original VapCap is the airflow geometry. Because it has an indent to hold the cap in place the Captive Cap has been made slightly wider than the original. This allows for slightly freer airflow through the stem, reducing draw resistance while retaining around the same vapour production. The increased airflow slightly improves flavour and provides more even heat distribution in the chamber with less singeing around the edges of the herb.
The final change is a more positive and obvious click when temperature is reached. This is again a function of there being a little more space inside the cap, allowing for more movement and the more obvious click.
