Is green gas propane or is it like propane?

Green gas is non like propane. It is propane. Dark-green gas is not R22, or Co2, or "CH2FCF3CH3" (equally seen on some bottles). It is but run-of-the-manufactory propane, with a dissimilar smell added.

And so it'southward really propane? How can y'all be sure?

Samples were sent to the Analest Laboratory at the University of Toronto where three brands of greenish gas (Jet, Green Power, Shooting Air) were analyzed with a gas chromatograph/mass spectrometer, an manufacture standard for organic gas assaying. All 3 gases were shown to be propane. Additionally 3 more brands have shown to be similarly combustible and exert the same pressure level. Test results, discussion and conclusions can be institute in the Lab Data section, please read the Laboratory Assay of Green Gas for more in-depth data.

And so, why should I fill my gun with propane instead of green gas?

If you use light-green gas, you're already using propane. Domestic propane is cheaper, comes in a safe container, and is available at whatsoever local hardware store. Airsoft bottled propane (green gas) has to exist imported (which tin take a long time).

Isn't it flammable?

Green gas has e'er been flammable. Now that we know it's propane, nothing has changed. You should never ignite propane/green gas, or release it near an open flame. However, propane is fairly safe for normal use - we already use butane (another flammable gas) in many consumer products, such as shaving foam and hairspray, and propane is used as an industrial refridgerant (it'south also known as HC290).

How come green gas smells different than fuel propane?

Fuel propane is scented with mercaptan odourants for leak detection. By itself, propane has very little odor. Different bottlers of fuel propane use unlike odourants and and so exercise green gas bottlers hence the dissimilar smells. Green gas and fuel propane are primarily propane so they all perform similarly in the terminate.

Some brands of dark-green gas are lubricated. Is propane?

Propane is not lubricated. However, the design of the AI Gungas propane adaptor makes information technology easy to mix silicone oil into your magazine fill accuse, and includes an instructional video detailing exactly how to practise it. Airsoft Innovations also carries ultra-lightweight silicone oil ideal for GBB maintenance.

What about my slide breaking, or seals beingness damaged?

Green gas is propane, we've been using it all the time, in that location is no difference. Add together a few drops of silicone oil, every bit shown in the AI Propane Adaptor instruction transmission, and your gun volition be just as well off as with "light-green gas". You shouldn't use propane/green gas in any gun that is not designed for higher pressures (eastward.g. united nations-upgraded Western Arms GBB's). Some GBBs are designed expressly for the apply of HFC134a (a lower pressure gas). Propane is not a adept substitute for HFC134a in GBBs designed for HFC134a.

Volition my gun perform the same on dark-green gas and propane?

I have some chrony results comparing propane from a Coleman stove tank and a brand of gas called "Shooting Air". Tests were conducted with a SVI 3.9" with metal slide shooting 0.25g bulletin board system. Shots were done with a completely filled magazine allowed to warm upward to room temperature for 30min. Shots were fired every 5 seconds to reduce cooldown.

Propane (fps) 289 285 283 275 273
Shooting Air (fps) 281 282 281 277 280

Volition propane damage my gun?

GBBs modified to handle dark-green gas (we really take to terminate saying green gas) are already propane fix. Certain GBBs in stock form (WA, TM to name a few) are not propane gear up. The higher pressure of propane can overstress a stock plastic slide and cause information technology scissure or completely break. Still, many users fire them on propane as they consider the performace/durability tradeoff acceptable.

Are propane tanks rubber to acquit in the field?

Yes. Most dispensable propane fuel containers feature overpressure relief valves which let propane to leak out earlier a can is over-pressurized and explodes. They are as well of heavy steel construction which withstands very high pressure level. Conversely, green gas bottles are thin walled aluminum without overpressure protection. In a few cases, these containers have exploded with frightening result. In one case, shrapnel from an exploded green gas can perforated a vehicle roof.

How come up nosotros've been using propane, and nobody knew?

The suspicion has floated effectually for a few years, but until now, no ane got around to really testing the stuff in a lab. Green gas has e'er been mislabelled, with fake chemical formulas and incorrect pressure specifications – nobody questioned them.

Tin can I see your test results?

Admittedly. I've compiled all my testing data, results and conclusions in the Lab Data section, delight read the Laboratory Analysis of Greenish Gas for more in-depth information.
