FAQ
Flamethrowers are federally unregulated in the United States — the BATF does not consider them a firearm. No NFA tax stamp, weapons license, or FFL dealer required. State-level restrictions only apply in CA and MD. For more details, visit our FAQ page.
The X15 runs on standard pump fuels — typically a diesel + gasoline mix. The user manual recommends starting with a 90% diesel / 10% gasoline blend for the most consistent ignition. From there:
- More gasoline → easier ignition and a more volatile burn
- Add napalm mix → run 50/50 diesel + gasoline with 1oz napalm scoop per gallon for a thickened fuel that clings to targets and creates a sustained burn — perfect for igniting hard-to-light material
Two propellant tanks complete the system: one 20oz CO2 tank (included) for fuel pressure, and a 14oz propane tank (purchased separately at any hardware store) for the pilot torch ignitor. Refillable CO2 tanks and napalm starter kits are sold separately in our Accessories section.
The X15 uses pressurized CO2 to propel fuel out of the wand — not a fuel pump. CO2’s expansive force is what gives the X15 its 50ft range. No pump-driven flamethrower can match it.
Each X15 ships with one refillable 20oz CO2 tank. The system runs best at 400–700 PSI (1,000 PSI max). CO2 pressure fluctuates with temperature, so cold-weather runs may need a brief warm-up before peak performance. CO2 tanks are widely available — paintball shops, sporting goods stores, and welding supply shops can refill them in minutes for a few dollars. Most owners keep a spare tank on hand for hot-swap during longer sessions.
Both run on diesel (or diesel + napalm mix) and use the same propellant system. The split comes down to power vs practicality:
- X15 is the practical workhorse — 50ft range, 3.3-gallon tank, the most popular flamethrower in the lineup. Built for everyday land work: brush clearing, prescribed agricultural burns, snow and ice removal.
- XL18 is the flagship — 110ft+ range, 0.5 gallons/second flow rate, the most powerful production flamethrower made. Built for buyers who want maximum range and visual impact: pyrotechnic events, public demonstrations, fire-crew training.
If you want serious firepower for practical land work, the X15 is the answer. If you want the biggest, baddest, longest-reaching flamethrower in the lineup, the XL18 is the better fit.

Power Up Your X15
Refills, upgrades, and napalm starter kits — compatible with both the X15 and XL18.
Why a CO2 System?
The X15’s 50ft range isn’t possible without CO2. The expansive force of compressed CO2 propels fuel further than any pump-driven flamethrower can — and the refillable, hot-swappable tank design means you can run uninterrupted all day.
Both the X15 and XL18 come with one 20oz CO2 tank included. Extras are available here.

A well-constructed product that comes with clear instructions, and great safety measures that grants anyone a fun time with responsibility in mind. Also pretty cool to own one and is a great conversation piece that sparks questions.

Real deal!

You make an excellent product & I am extremely happy that I was able to obtain the X15.

Ahhhhhhmazing. This is my 1st real thrower, and I tell you that they are 2nd to none. The quality, engineering, and attention to detail makes the difference. It’s heavy when filled but that won’t matter because the excitement outweighs it at every turn. I promise you no one will have a bonfire without you lighting it. It’s surprisingly user-friendly and if you pay attention to ratios and mix it’ll really add to the experience. As far as customer service I can’t say enough great things about them, I’ve had this one for awhile and a seal deteriorated (nothing remotely dangerous I might add) and they’re quick to get the replacement part to me. Bravo throwflame…..yeah time to save for an xl18 now

Purchased an X15 Flamethrower and I am very satisfied. Definitely didn’t cut corners on solid design. Honestly a pretty massive amount of power and quite impressive burn time. You can tap the trigger here and there and the fuel would last a good bit with quick effects to anything it touches. Can’t wait to try my napalm mix!!! Great product.
Jim Gibson (verified owner) –
Outstanding product! Exceptional quality! Incredible performance. I purchased the X-15 for burning the snake grass around my pond, it is a job on the ranch that we hate doing. Since we have purchased the X-15 my wife and I enjoy doing the work and fight over whose turn it is to burn. And we have our friends asking if they can come watch.

Looking for a gift for the person that has everything. Well.look no further the X18 is it. Using it is the most fun you humanly have. Once you have one you will wonder how you ever lived with out it. It ships quick so no long wait for your purchase and the customer service is quick to respond and always ready to help. It’s simple to use and more fun then words can describe.

This thing gives a while new meaning to the phrase “light up my life”. I can’t describe the pure joy of burning so much stuff with just the squeeze of a trigger. SO WORTH IT! I love my flamethrower. 49 lbs of backpack mounted joy!
