The DynaVap Tectonic Stem is a specialty stem and a great addition to your vap cap collection. The Tectonic not only looks super rugged and heavy-duty but also has a bunch of functionality and "tweakings" that you can play with. The airflow can be controlled with a ring adjusted to a single or double port. The Tectonic inside features an airflow control spiralized air chamber and an o-ring-free condenser.
