This stem does... (almost) everything!
The Revolve by MAD Heaters is our standout DynaVap stem, with more features than any other stem, all of which work to perfection, we don't have a single complaint about these! Top notch design and manufacture leading to excellent vapour quality and a device which is a pleasure to use... and the cooling helix provides the coolest vapour of any stem (we've found) out the box!
Bundles or Individual Stems are now available! Please select your desired option from the menu. Don't miss the Reload accessory which is now available!
Why are they cheaper?
Not everything goes to plan and while every effort is made with quality control some products make it through the net. This listing is for Revolve stems which have very minor visual defects (please see last 3 pictures for close ups) on the finish around the fins where there are very tiny aberrations as the PVD coating has not adhered fully due to the finish. They perfectly functional and otherwise identical. We plan to stock the regular ones too when there is enough stock available but for now we thought we'd grab some of these and offer a great deal on them since we know some of you, like us, don't really care about minor visual defects and are focussed on functionality!

Features with DRC (Draw Resistance Control) Airflow Tube (installed)
Please also check out the MAD Heaters Revolve manual for full details and diagrams. We have paraphrased this below in an attempt to further clarify the information.
DRC Airflow Tube - The first thing you need to know is what this is. The DRC Airflow Tube sits inside the mouthpiece and allows for further fine tuning of the airflow. For example when you have shut the airflow port down to it's lowest level, if you find you want further restriction you can adjust the DRC Airflow Tube to shut this down even more! This feature gives it by far the most adjustable airflow of any DynaVap stem.
||This setting pulls cold air in through the port, then up the centre of the stem before mixing with the vapour and being pulled around the helix, cooling against the body, before entering the mouthpiece.|
On bypass the cold air comes in through the airport and straight into the mouthpiece, while the vapour travels around the helix. This provides a blast of cool air mixed with your helix cooled vapour.
The airport is now shut, no fresh air is added, the vapour passes around the helix to be cooled before reaching the mouthpiece. Great for mouth to lung inhales.
Please check out the DRC Airflow Slideshow to see the different airpath options visualised.
Features with the Direct Airflow Tube (included, not installed)
The Direct Airflow Tube replaces the DRC Airflow Tube inside the mouthpiece providing a more direct vapour pathway providing a hotter more traditional DynaVap experience. As with the DRC Airflow Tube, please check out the MAD Heaters Revolve manual as this has full information and more images/diagrams.
||Direct Open - Vapour passes straight down the centre of the stem while cold air is brought in through the port, direct to the mouthpiece.|
||Direct Bypass - While vapour is being drawn straight down the centre of the stem, cold air is drawn in through the intake port where it travels up around the helix, providing a little cooling to the vapour inside the centre, before mixing with the vapour and travelling down the centre of the stem to the mouthpiece.|
||Direct Closed - The airport is closed, vapour is drawn down the centre of the stem like a regular DynaVap for that toasty vapour..|
Please check out the Direct Airflow Slideshow by MAD Heaters to see these visualised.
Please check out the MAD Heaters Revolve manual page so you can see all the detail and incredible functionality of this design. We have only provided an overview. Follow the link above and scroll down to the bottom of the product page to find the "Manual" tab.
- If the cooler helix or any other part is difficult to turn or remove from the body; warm it up by running an extra session to heat the residue causing it to stick
Using and regularly cleaning or replacing the reclaim catcher mesh will significantly reduce the regularity of maintenance cleans required on the rest of the stem
- Due to the finishing process every Rainbow stem is unique and varies in colour
- Before first use please make sure to clean the stem thoroughly with isopropyl alcohol to remove every residue from the machining and coating process
- The Glass body might leak a little air on the closed setting due to glass manufacture tolerances
- Never rock the tip side to side while removing it as you might break the glass
DynaVap Tip and Cap are not included, these are required for use!
If you're looking for the best dynavap stem on the market this is the one. I have an mvs too and this is 10 times better. Cooler vapour and nice tasty hits which is what it's all about.
The minor defects are negligible on the titanium stem. I'd never have noticed them if it wasn't in the description and I'm sure I'll be adding worse marks to it with heavy use.
Top service as usual from RVS 🙏
Ahh thanks for the review, I'm glad you agree it's the one!
After encouragement from Matt I bought a rainbow coloured version of this stem and I'm very glad I did. I still can't see any meaningful defects but I can see stunning build quality and an amazing level of cooling once I got it dialled in to my liking. It even works well with my 21 Omni ti tip which is unusual. I'm still amazed by it after weeks of constant use, you really do need to use a glass stem/bong setup to equal it..
Highly recommended great stem/bundle and fantastic service. Will definitely use these guys again.
Also couldn’t find anything wrong and I have Beady eyes
Ive been using this daily (3-4 bowls per day) for over a month, and everything about this stem is exceptional.
I got the bundle with rainbow color, and typically use the glass tube, things that stand out from the standard M 2021 stem:
Customization: there's so many options, almost too many, but you are able to get your draw resistance and flow just right, and really easy to change on the fly
Flavour: Its better, not by a huge amount, but it is noticeable (using glass body)
Cooling: wow huge difference IMO, can chain back-to-back hits without burning my fingers off now yay!
Defects: what defects - there are zero visible ;)
Glass body: this is huge, can tell when its ready for cleaning, easier to adjust the draw resistance since you can see the hole, can see when vapour is depleted whilst drawing, (eh cause its see-through)
Build quality/aesthetics: looks and feels great. I'd prob swap out the glass for the default titanium body when travelling, as it seems bullet proof.
This website: Matt offers simply amazing customer service, very accommodating, very friendly, 100% has my customer loyalty from now on
Overall: just get it, its a total game changer!
Pair this with the iSpire wand - it's fantastic, gets 1-2 hit extractions, similar or better than a standard torch
Thanks for the nice detailed review, I'm very glad you like it as much as I do! Here if you ever need XD - Matt
A second but my QC ain't as good as there's because I only found a tiny imperfections on the fins and that was after a long time. Well chuffed with my bundle.
Wont say anything about the Revolve except trying is believing
