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.

Long burn time of 60 seconds you can really get a lot more done wether it be brush piles or clearing fence rows. The X15 is a very useful tool….and fun at bonfires.

Do you need a flamethrower? No. Not really. But it is worth every penny because it is awesome. And someday you’re going to die and you don’t want to look back with regrets.

got my x15 a few weeks ago–shoot it almost every day–very intense in person, videos dont do it justice–glad i made the purchase, a real hit at parties !!!
Joe W (verified owner) –
I was very impressed with my purchase of my X15 flamethrower. I would have given it five stars in a heartbeat but I bought it less than a year ago and the reason was because it was the biggest and best. Now there is the XL 18 Which shoots twice as far as my brand new X 15. It just really bums me out because the X15 was a one time purchase (another flame thrower purchase will inevitably end in divorce). I am waiting for the upgrade and I am really hoping it is at a very reasonable price, So reasonable that there is a possibility of it going almost unnoticed on my JOINT account. It would be great to be able to trade in any parts no longer needed for a discount on the upgrade. Please don’t misunderstand me the X 15 is an awesome product! I am just bummed because of my particular situation.

No problems at all with the napalm, although it’s easy to make homemade, it is Handy to have on hand. Would recommend any first time user to pick up a container.
