The other night my friends and I where burning trash outside my house when I tossed a can of green gas in the fire, it was about 97% empty. We waited.. and waited. expexting it to just pop the top and fly like a rocket when.. KAABOOOOOM! sounded like 4 12ga shotguns at once throwing up a 15 foot fireball and shooting the top of the can at the house.
It was not near as big as other explosions we have made but we sure as hell where not expecting that from that can and it was an empty can! Its the Team SD large green can.I would take a picture of the parts of the shreaded can but the camera's acting up again.


My question is.. What the hell is in this stuff?!?

We used to shoot at the empty cans with .22's because they would spin around but I know what im doing with them now!


hey... I dont think I have ever posted in the airsoft section..

Airsoft-Innovations FAQ said:
Green Gas is Propane FAQ

1. Is green gas propane or is it like propane?
Green gas is not like propane. It is propane.

Green gas is not R22, or Co2, or "CH2FCF3CH3" (as seen on some bottles). It is merely run-of-the-mill propane, with a different scent added

2. So it's really propane? How can you be sure?
Samples were sent to the Analest Laboratory at the University of Toronto where 3 brands of green gas (Jet, Green Power, Shooting Air) were analyzed with a gas chromatograph/mass spectrometer, an industry standard for organic gas assaying. All 3 gases were shown to be propane. Additionally 3 more brands have shown to be similarly flammable and exert the same pressure.

Test results, discussion and conclusions can be found in the Lab Data section, please read the Laboratory Analysis of Green Gas for more in-depth information.

3. So, why should I fill my gun with propane instead of green gas?
If you use green gas, you're already using propane. Domestic propane is cheaper, comes in a safe container, and is available at any local hardware store. Airsoft bottled propane (green gas) has to be imported (which can take a long time).

4. Isn't it flammable?
Green gas has always 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 cream and hairspray, and propane is used as an industrial refridgerant (it's also known as HC290).

5. 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 smell. Different bottlers of fuel propane use different odourants and so do green gas bottlers hence the different smells. Green gas and fuel propane are primarily propane so they all perform similarly in the end.

6. Some brands of green gas are lubricated. Is propane?
Propane is not lubricated. However, the design of the AI propane adaptor makes it easy to mix silicone oil into your magazine fill charge, and includes an instructional video detailing exactly how to do it. Airsoft Innovations also carries ultra-lightweight silicone oil ideal for GBB maintenance

7. What about my slide breaking, or seals being damaged?
Green gas is propane, we've been using it all the time, there is no difference. Add a few drops of silicone oil, as shown in the AI Propane Adaptor instruction manual, and your gun will be just as well off as with "green gas".

You shouldn't use propane/green gas in any gun that is not designed for higher pressures (e.g. un-upgraded Western Arms GBB's). Some GBBs are designed expressly for the use of HFC134a (a lower pressure gas). Propane is not a good substitute for HFC134a in GBBs designed for HFC134a.

8. Will my gun perform the same on 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 bbs. Shots were done with a completely filled mag allowed to warm up to room temperature for 30min. Shots were fired every 5 seconds to reduce cooldown.

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

9. Will propane damage my gun?
GBBs modified to handle green gas (we really have to stop saying green gas) are already propane ready. Certain GBBs in stock form (WA, TM to name a few) are not propane ready. The higher pressure of propane can overstress a stock plastic slide and cause it crack or completely break. Still, many users fire them on propane as they consider the performace/durability tradeoff acceptable.

10. Are propane tanks safe to carry in the field?
Yes. Most disposable propane fuel containers feature overpressure relief valves which allow propane to leak out before a can is overpressurized and explodes. They are also of heavy steel construction which withstands very high pressure.

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, schrapnel from an exploded green gas can perforated a vehicle roof.

11. How come we've been using propane, and nobody knew?
The suspicion has floated around for a few years, but until now, noone got around to actually testing the stuff in a lab. Green gas has always been mislabelled, with fake chemical formulas and incorrect pressure specifications - nobody questioned them.

12. Can I see your test results?
Absolutely. I've compiled all my testing data, results and conclusions in the Lab Data section, please read the Laboratory Analysis of Green Gas for more in-depth information.
And what happens when you leave a can of green gas on your dashboard on a warm day (75 degrees)

Also, propane has a SLIGHTLY lower PSI than GG, due to the silicon oil. The oil takes up room, which allows for slightly more pressure.

damn.... i just learned something. i shouldn't be using green gas in my WA replica M92FS.....


/shrugs


it kicks like a mofo
Well you can go to a weaker gas like 134a. But all my WA's run greengas just fine. Haven't cracked a plastic slide yet (knock on wood). Same goes for my TM GBB's. BUT other Japanese Brand GBB Handguns will have noticeable durability problems running Green Gas. In Japan they don't have Green gas, they build most guns around the weaker 134a gas, so for peace of mind it's safe to run weaker gas.

Or upgrade to metal. That is always the better option.

Better? That would mean all KWA or WE GBB's are better since they ship with Metal Slides? :rolleyes: I'll stick to TM,WA and Marushin's GBB's as always... I can electively upgrade to metal slides if needed.

I personally don't like any of my GBB's with metal slides due to the effects on rate of fire/slide cycling.

Yeah cat watch this.. kinda sad:

ORCA, I meant to upgrade the WA with a new metal kit. Not to go sub-par with cheap chinese crap.

Thus the reason I made sure to address your non defined stement:

A new person to airsoft could have easlily taken that comment to mean something else.

I still don't suggest anyone getting a metal slide unless they HAVE to due to breakage. The amount of things you need to upgrade internally just to cycle the heavier metal slide properly, still doesn't justify the lowerd ROF to me. This includes WA's, especially all WA's from SCW3's and later.

Now I know there's a whole bunch of airsofters that are into "Realism" and love to upgrade everything to replicate a real steel gun as possible, but that's a toss up of form over function and vice versa.

You can still have function AND form, but I can guarentee it'll cost ya.

BTW-ORCA-I used to do custom work, and in order to get a SCW V2 or higher working with metal, you need to spend about 4-500 on the slide and frame, and another 500ish on internal parts. I HAD (past tense) a WA 1911 that was full metal, fully upgraded internally, magwell, and 6 mags. Total cost was around 1300. But, that was a while ago.

Sounds like it's good you stopped doing custom airsoft work dropping that much on a WA...

I don't really think this thread needs to turn into a pissing match. You can toot your own horn on w/e you did with airsoft. Some of us actually work on this stuff professionally and was only making sure EVERYONE could benefit from the info, not just peopel who could read into the non descript posts.

The topic questions were already more then answered. If you really want to show off your airsoft w/e, there's other more appropriate topics.
