The 2nds Quality Perf caps are what we used to dial in the aesthetic position of the perforations. The perforations are not aligned and may run into the Dynavap logo or Low Temp graphic, but this does not affect function. 

Modification -

• Perforated Faded Geometry for increased airflow and flavor
• Simrell Lasered Identifier on the top of the cap 
• Polished
• Captive Cap 

With these modifications, it will allow for more heat cycles, extend the life of the material in your chamber, increase flavor and airflow. The low temp perforated cap is compatible to all standard dynavap tips. I reccomend using the perforated cap paired with Titanium tips for Torch heating and Stainless Steel tips for Induction heat.

The Cap is made of medical grade stainless steel. The Dynavap signature Cap is engineered to “click” when heated to the right temperature, and features the multitasking digger-outer.

Note: Sometimes the Cap will click twice. This is normal.
If your new cap is loose, give it a gentle squeeze to adjust the fit.
