Simrell Stainless Steel FMJ – DynaVap Attachment
A revolution in the world of analog vaporization has become a reality. Discover the Simrell Full Metal Jacket (FMJ) in stainless steel version – an accessory that will forever change the way you use your DynaVap VapCap.
Simrell Collection is a brand that has defined the concept of “premium” in the world of vaporization accessories. The FMJ (Full Metal Jacket) model is an advanced thermal attachment designed to eliminate the biggest pain point for manual vaporizer users: the need to rotate the device during heating. The version made from high-grade stainless steel combines incredible thermal efficiency with durability and aesthetics that will withstand years of intensive use.
No More Rotating: Simple and Repeatable Technique
The biggest innovation introduced by Simrell FMJ is the complete elimination of the “rotation technique”. In a standard VapCap, rotating is necessary to avoid burning the herb. With FMJ, this problem ceases to exist.
The attachment works like a thermal buffer that stores heat from the torch and releases it evenly to the heating chamber from all sides simultaneously.
- Aim for the logo: To heat the device, simply direct the torch flame at the Simrell logo visible on the attachment.
- Stability: You don’t need to rotate the vaporizer in your fingers. This is an ideal solution for people using water filtration or using a vaporizer outdoors, where precise heating can be difficult.
One Hit Extraction: Complete extraction in one cycle
Have you dreamed of your economical DynaVap generating vapor clouds as thick as from a desktop device? Thanks to the large thermal mass of stainless steel, FMJ maintains temperature much longer than the standard attachment.
This allows you to achieve so-called One Hit Extraction. This means you’re able to use the entire contents of the chamber during one long and intense inhalation. The herb after such a session is uniformly dark brown, which indicates maximum efficiency. You save time and lighter fuel while getting a stronger effect faster.
Stainless Steel: Purity and Durability
Choosing stainless steel is a decision for years. Unlike copper attachments, steel:
- Does not patina: You don’t need to worry about the metal darkening or the need for regular polishing. The FMJ in steel retains its raw, industrial shine.
- Is scratch-resistant: The hardness of steel makes the attachment much more resistant to mechanical damage than soft copper.
- Ensures clean taste: Stainless steel is a chemically neutral material, which guarantees that the flavor profile of your herbs remains intact.
Compatibility and Installation
Before purchasing, make sure you have the correct cap model. Simrell FMJ was designed with millimeter precision.
- Compatible with: Captive Cap attachments. These are caps with characteristic notches on the sides that allow the FMJ attachment to anchor securely.
- Not compatible with: Older Cap-type caps (without notches) and Low Temp caps, unless they are in Captive version.
- Installation: It’s incredibly simple – just slide the attachment onto the Captive Cap. Thanks to precise fitting, the FMJ stays securely in place and doesn’t fall off.
Instructions and Safety
To get 100% out of Simrell FMJ, follow the steps below:
- Install the FMJ on the Captive Cap (the Simrell logo should be visible).
- Fill the chamber with your favorite herb (don’t pack it too tightly to maintain airflow).
- Use a torch lighter (preferably with a single flame) and direct the fire at the “S” in the Simrell logo.
- Don’t rotate the vaporizer! Keep it still.
- Wait for the click. Thanks to the steel mass, the click may occur a bit later than usual, which means deeper heating of the chamber.
- Begin inhalation. Remember that the attachment will be hot much longer than usual – don’t touch it directly after the session!
Simrell Stainless Steel FMJ is a “game changer” for every DynaVap enthusiast. Order today and take your vaporization to the next level!
