Simrell →The Simrell FMJ (Full Metal Jacket) by Simrell is not a standalone vaporizer, but a high-quality metal body for DynaVap VapCaps. Its solid construction significantly improves heat retention and vapour quality compared with the original DynaVap body. Compatible with dosing capsules and water filter adapters. Prices start at around 13 euros for basic versions in the price comparison.

What is the FMJ?
The Simrell FMJ is a replacement body for DynaVap Tips. You therefore need a DynaVap Tip (the actual heating chamber) to use the FMJ. It replaces the standard DynaVap body and provides better heat retention thanks to its thicker metal. The additional metal mass acts as a heat reservoir around the Captive Cap; the FMJ itself does not contain a heater.
Research context: A study in the Journal of Pharmaceutical Sciences (Hazekamp et al., 2006) showed that vaporization at controlled temperatures releases more than 95 % of the desired active compounds, while largely avoiding combustion by-products. Source: PubMed 16637053
Heat retention and vapour
The major advantage of the FMJ is its mass. More metal means more stored heat. This results in longer heating cycles and denser vapour with each draw. The difference compared with the standard body is particularly noticeable at lower temperatures. It cools down more slowly, which improves extraction.
Compatibility
The FMJ fits all common DynaVap Tips. Dosing capsules work as usual. A 10mm or 14mm adapter allows it to be connected to water pipes. It is heated like any DynaVap, using a lighter or induction heater — the Click from the Tip indicates the operating temperature.
Build quality
Simrell manufactures it in the USA from stainless steel or titanium, depending on the version. The surface is precisely machined and feels comfortable in the hand. Its greater weight compared with the standard DynaVap body gives it a premium feel. It is a worthwhile investment for DynaVap users who want greater vapour performance.
