Propane w/ plastic slide/barrel
 

Hey i hear everywhere that green gas has the same chemical composition as propane and i hear its exactly the same but i also hear everywhere that you need a metal slide i was wondering if it would work with a plastic slide?

thanks

It will work BUT it will be only a matter of time before you slide will crack

This is an old debate on this forum, I have troubbles believing that propane and green gas are the same as if they are the same then you would need to upgrade for green gas as well. Green gas is not propane it will not damage your gun unupgraded. if your gun runs on say duster gas then yes green gas will be bad.

Am I drunk or did that make no sense?

What are you on dude? The gas formerly known as green, and propane exhibit the exact same pressure at multiple different temperatures. Ergo, wear on the gun is going to be the exact same.

I think someone was sniffing the green gas....

Metal slide = propane
Plastic slide = duster

That's the rule I go by for GBBs and I have yet to break one.

If your gun is designed for duster you DO need to upgrade for green gas or propane...ideally

Propane breaking plastic guns seems to be random based on tiny flaws in the plastic, I have heard of people with the exact same gun getting completely different mileage out of em. One has the slide break after 50 rounds on propane and another gets to 10 000 and still going strong. I've used propane in all my GBB's metal or not and not had a single thing break, a few hundred rounds through my TM Hi-Capa 5.1 and another few hundred through my KSC G19 and maybe 200 through my KSC M93r running mostly full auto (all my other GBB's where metal.)

if you buy a plastic slided gun an plan to upgrade to a metal slide in the future, then sure go for propane and who knows when it will break but when it does you have a replacement...

Duster gas is just not strong enough for woodland type games thats why many people choose to use more powerful gases even when they are risking their plastic slides.

i myself have experienced no plastic slide breaking from propane. around 500 rounds on my KSC USP Compact, around 500 on my TM M92FS tactical master, 1000+ on my TM Desert Eagle, and 1500+ on my KSC Glock 19's before upgrading to metal. Unsurprisingly the plastic slide showed no signs of breakage prior to FMU

Yes and green gas is propane. however fps comparisons show that propane is a tad more powerful than green and propane stinks.lol

It's a bit hard to say. Some GBBs have chronic issues with propane. For instance the slides for TM M9 and M9 variants (Tac Master etc) are known to eventually fail under propane. Western Arms heavy weight slides eventually crack, but for some reason their chrome plated 0.45 slides seem to be really durable. I suspect that the chrome plating prevents WA from adding metal powder fillers (to increase weight) because they interfere from the chrome plating. Because of this, you can have more plastic chains entangled with each other instead of fewer wrapped around sharp poorly bonded metal bits. I have never heard of a 3.9" full auto Prokiller (lightweight slide) or any chrome plated (mirror shiny not satin shiny) slides breaking from propane.

There's also the TM Hicapa build which has been out for more than a year with no slide failures not due to drop impact.

In short, you have to be more specific in your question as various models weather propane differently. Try asking: "Do you have a INSERT GBB MODEL and how long have you used it before the slide broke?" kind of question. Otherwise you get a mess of generalized observations mostly about GBBs you may not be interested in.

Oh we know your def drunk, but that still doesnt make any sence :)

I have used this KWC Colt National Match with good 40-50 mags of propane, it has not yet broken on me, and when I took it apart, everything looked fine. Gun was cleaned well and lubricated and then tested with duster gas.

I prefer duster for this gun because I think it was built for that type of gas, reason being is that it simulates actual gun fire by releasing a visible stream of gas from the hammer and the chamber area when the trigger is pulled. I find this extremely cool, because this is not possible with propane. I don't know if other ABS guns do this with duster gas aswell, but it's my 1st ABS GBB I ever owned and I love it.

Anybody else on here has 1 like this?

HFC134a = 350fps @ 23C
Propane = 390fps+ @ 23C

future mods: custom metal slide, high flow valve, ported barrel, custom grips

Green gas CH2FCF3CH3 (Methylated Tetrafluroethane) @21 deg C= 100psi
Propane CH3CH2CH3C3H8 @ 21 deg. C= 138psi

Hmmm..... dose this make more sence?

still don't believe me? LOOK IT UP.

using gas that has a higher pressure than the seals are designed to handle will eventually damage ur gun.

propane is c3h8 for the chemical formual the prop comes from the fact it has 3 carbon groups. Basic high school chemistry

here's a little thing about propane and green gas my friends always telling me

green gas is good for lowering fps works extremely well in winter and will not cause any damage to your slide from a hard kick o mater how its tuned

propane this gas will increase your fps give you a harder kick and will freeze in below 0 temperatures

red gas i will quote this one "if i ever catch you with red gas i will kill you"

duster gas hasn't yet come up

Read up on various gases, and green VS propane, in the Information section. You will find interesting and correct facts that way.

The good looks real nice actually, though with regards to the escaping gas its probably not good. It means that the mags aren't properly seating and probably need a little silicone oil on the rubber or perhaps have high flow valves installed. Ideally, the pressure should be focused down the barrel. Having said that, if you like the way that looks (just don't smoke and shoot at the same time) then what the heck, enjoy :smile:

Your first link doesn't work. I'm not exactly sure what you're trying to say with your wikipedia link.

Guys... green gas and propane are the exact same thing. This has been proven by MadMax/Carl with gas chromatography-mass spectrometry testing at UofT.

Facts:
-The molecule on green gas cans is unstable and cannot exist in nature
-Green gas and propane exert the same pressures at multiple different temperatures
-Green gas and propane combust in the same fasion
-Green gas and propane have practically identical spectrums as found throught the GC/MS testing

Conclusion: Green gas is propane.

I'm guessing you're reading the side of your green gas can. Normally you're supposed to be able to trust labels which show you what's contained in your purchases, but in the case of green gas, the molecule definition is a blatant lie.

CH2FCF3CH3 is not the chemical formula for tetrafluoroethane. The structural molecular formula is: H2FC-CF3 http://encyclopedia.airliquide.com/e....asp?GasID=141

I think you're allowed to rearrange it to read: CH2FCF3, but there is an extra CH3 group appended to the end of the can label which is not correct. If you recall your highschool chemistry, carbon does not have enough valences to hang onto the extra CH3 group.

If you directly measure the pressure of your GG can, you'll also note that it does not exert 100psi at 21C. It would be exerting around 120psi just like propane. Propanes molecular formula is C3H8 not the wonky one you stated. You'll also find that pretty much every brand of green gas is similarly flammable to propane. HFC134a (tetrafluoroethane) is not.

You've clearly found industrial references to propane. Have you noticed that there are no industrial references to CH2FCF3CH3?

Unforunately my website is still offline:

If you don't want to believe my research because of the conflict of interest issues with me selling propane adaptors, that's fine. However you should also realise that green gas bottlers are also businessmen who may be selling a product under false pretenses. At the very least green gas bottlers should properly label their containers warn the public that they are using a flammable gas product. They should also use better containers. Airsoft GG containers are dangerously thin. There have been some cases of them bursting with dangerous results.

I bought one of your propane adaptors in one o me first purchases from the ASC, it works great.

so you admit that green gas is propane then lol?

Ha ha ha no. i admit to nothing aside from stirring a little sh** and promoting a good propane adaptor. (just remember to add silicone oil to keep ur gun working good.)

I have a feeling that Shadow is confusing green gas with duster gas. Propellants aren't very well defined in airsoft.

2 drops every 10 mags' worth. trust me, i over-lubed my USP once, not fun.
