Gas For Taiwan Guns

[BigRich]

Is there a difference in the gas for the Taiwan made gas guns? Can you use green gas or propane? Thanks Rich

[Hawkmoon]

So far, all the gas guns I have tested and handled use green gas, irrespective of country of manufacture. John has mentioned propane, but I have the impression that's a conversion of some sort. No doubt he will be able to provide more insight.

[John]

Let's clarify this issue.

Taiwanese guns are made for Green gas. Japanese guns are made for HFC 134A.

With that said, if you were to make a chemical analysis of Green gas, you would be informed than in reality it is propane, with some silicone lubricant added, to take care of the lubrication needs of the pistols. So, you can use propane instead of the Green gas, but you have to remember to add a bit of silicone oil yourself, since it is not in the gas now.

The conversion that Hawkmoon refers to, is needed when you want to convert Japanese pistols (like Western Arms) to use Green gas or propane. In Taiwanese pistols, no conversion is necessary. For the Japanese ones, if the pistol has a metal slide, then you do not need to do anything, if it has a plastic one, you need to install a "Flow restrictor" to reduce the force with which the slide recoils.

I hope this clarifies the matter.

Just got my WEI-ETECH HI CAPA 5.1 . I'm so impressed with this gun. I have a question about the CO2 cartridge mag, is the velocity the same as using the gun with propane? I didn't order the mag from AIRSPLAT yet was just wondering about the versatility of CO2 cartridge. For the price its a great deal.

Thanks,

Rich.

The Airsplat.com site, gives 10 more fps when using the CO2 magazine. So, the difference is minimal.

[BigRich]

How many shots from one cartridge? Trying to decide If I shuold bye aCO2 mag. Thanks Rich

[John]

I do not remember exactly, I would say about 2 1/2 and 3 mags, but I can't recall.

Taiwan pistols use hi-powers gases.
- Green ET-1000 and more
- Red ET-1600 and ET-2200
- Many pistols can't use black gas ET-2600 (HFC M190, WE Hi-Capa 5.1)
- If possible (magazine construction) CO2-cartridges

Japanese pistols for HFC134A only. Many models of WA can't use green&red with upgrade rubber ring.

Wait are you stating that WE Hi-Capas CAN use Black gas or can't? And could you possibly give me an average fps increase of each gas compared to the hfc134a? Do you guys think that the CO2 mag is worth it?

[John]

The CO2 mag is a convenience item to have. If you run out of the standard gas, you can always have some spare CO2 cartridges and play around. WE Hi-Capas can use Propane or Green gas fine, I have no idea what black gas is. I am not too experienced in these things.

[Sakagami]

So is propane more powerful than green gas or CO2? I might get the Co2 mag for the small jump in power and the less chance of the green gas freezing.CO2 cartridges are also obtainable at Wal-Mart, so its more convenient.

[John]

Green gas is actually propane, with some silicone oil additives, to lube the action of the pistol. Both of them (green gas and propane) are more powerful than hfc 134. If you go the propane route, you may want to read this:
