The FMJ is a revolution in ease of use for all Dynavap vaporizers with a “Captive Cap”.

Simply slide it over a captive cap and it’ll snap into place, eliminating the need to rotate the cap at all. The thermal retention of the copper jacket holds heat for a full 60 seconds, allowing you to get a 1 hit extraction from the dynavap cap.

The Logo on the FMJ is actually an Aim point. Simply take a single flame lighter, point it at the S logo (( making sure the color change of the copper is the same size as the S )) and you will get perfect results every time!

The FMJ accents the cooling of the Simrell Vortex System really nicely.

Meet the FMJ. A Full Metal Jacket constructed to extract a full chamber in 1 heat cycle. Made from 99.99% Copper, the FMJ transforms your cap into a powerful one-hitter. How? Simply slide the jacket onto a CAPTIVE CAP. The FMJ will change the way you use a DynaVap vapcap.

Why Copper?

The use of copper on the cap eliminates the need to rotate your tip to get an even heat up. It acts as a thermal reservoir that holds heat and evenly distributes it, allowing YOU to choose how dense and dark you want your extraction during your first heat cycle.

The copper jacket also acts as a better buffer for combustion, allowing you to worry less about your reaction time after the click. 

Heat It Up

Simrell's signature logo is more than a symbol of authenticity. The logo on the FMJ serves as a visual reference point for your torch.

For the perfect heat up, direct the flame at the Simrell logo. As the copper heats up, it will begin to change color. When this “hot-spot” is the size of the logo, you're at the perfect distance to heat the cap. Once it clicks, you will have approximately 60 seconds to clear the bowl.

Advanced Heat Method 

By covering the airport on your stem, you will increase the pressure and the temperature inside of the chamber, resulting in the darkest roast possible. If you leave the airport wide open during your session, you will have lower pressure in the chamber and get a lower temp less dense extraction. To modify your roast, adjust the chamber heat/pressure by adjusting your airport usage.
