Shell-Shock DynaVap Stem - With Adjustable Airflow Ring

Unit price  per 
Tax included. Shipping calculated at checkout.

A new creation from BB Vapes BRVND, the Shell Shock DynaVap stem serves as a high quality upgrade to your original stem. This is a limited run!

Adjustable Airflow

The Shell-Shock has an adjustable airflow ring allowing you to fully customise your vapour experience.  This ring is well positioned for convenient access during use, allowing you to easily close it down with a finger mid draw, if desired. It holds it's place well so can usually be found where you left it. To fully close the airflow ensure the ring has been turned so the hole is opposite the one on the stem (around the other side). We have found the black Shell-shock stem forms a full seal more easily in more positions of the adjustable ring due to the extra thickness of the anodised coating.  

Heat dissipation

Made from thicker stainless steel the Shell-Shock stem helps dissipate more heat from your vapour, providing a cooler and smoother vaping experience. It has an integral heat heat sink at the hot end which dissipates more heat away from the stem, keeping it cooler during use. These heat dissipation properties make it suitable for multiple back to back sessions.  The Shell-Shock stem also has it's own high quality internal condenser tube which is slightly thicker and has a smaller diameter, adding to the cooling effect. The smaller diameter and thicker metal means more vapour makes contact with the cool condensing tube reducing the temperature more than the originals. 

The DynaVap end of the stem has a spiral machined into the inside to help cool the stem and vapour. This works by helping break up the airflow moving it around the whole stem, adding extra cooling. 


This stem has been designed with functionality in mind, having multiple grip designs it is comfortable to hold and use. At the mouthpiece end there is a matrix/grenade style grip which provides excellent purchase. The hot end has been milled with grooves to make rotating the Shell-Shock in your hand while heating a simple task. Finally the stock mouthpiece provides excellent functionality. Primarily it is very comfortable as a mouthpiece, perfectly suiting the slightly restricted draw style of the Dynavap. Secondarily it fits well into your hand and serves as an extra point for stability and easy rotation of the Shell-Shock while rotating it during heating.. This is a 510 drip-tip so can be replaced as desired if you have another you'd rather use. 


Pretty much all of the above serves to make this an attractive stem, it is a thing of functional beauty. If functional beauty isn't your thing it's also available in a range of colours! Lets face it though, it looks great, especially if you like the chunky militarized look. 

Water Tool Use

These are compatible with our 14 and 18mm (does both) Silicone Water Tool adapter for V4 Crucible. The Adapter replaces the 510 drip tip. It sits in loosely and forms a seal when held against or place upside down in a water tool.

Before I mention the Shell-Shock DynaVap Stem I gotta give a shout out to Matt. Great customer service, dude. Thank You. Your fast reply to my questions help me decide on purchasing two initially, and Im purchasing a third. Now to the Stem. To anyone with a DynaVap, get this stem before they're gone. Hard to combust easy to enjoy. The terps are amazing......hits are smooth. Feels good to the hand. My girl took the first one I bought. Pair this stem with a 2020 M. Thats it.

XD You're very welcome. Love my shell-shocks.


Great airflow, nice weight and gorgeous looking!

BB Vapes Shellshock Stem

Love this stem . Nice weight to it and love the way you can fully close the airflow . You can also add a longer 510 drip tip if you need to cool the vapour a bit more , I’m happy with the tip provided though .
Amazing service and best price from Matt , top bloke . Make sure and get one quick as they won’t be around for long .

Shell shock

I bought this not expecting too much to be honest, but I was really impressed with this, gives a great draw and best of all you can open and close the carb hole, this performs much better than the factory dyna_vaps.
Sit nice in the hand, not too heavy but feels really solid, a little heavier than a omi and a decent price, can’t think of any bad points,
