The DynaVap Captive Cap introduces key features for an improved DynaVap experience. If you’ve ever had a Cap pop off of your DynaVap M during a heat up, you’ll really appreciate the new design of this cap. It comes with a small indentation on either side to secure itself to the tip and prevent any mishaps. The Captive Cap also has enhanced shaping for better heat distribution as well as upgraded tactile responses for a more distinct “click” when heating and cooling down. If you’re looking for a replacement cap or just want something new, the Captive Cap is a great option.
