Okay I own a maruzen Mp5k and I am not sure what type of gas to use with it, I have heard the nozzles are EXTREMELY weak in these guns. When I looked it up I saw you should use HFC 22 which I have never seen before.
Basically, is this the same as HFC 134a or is it a completely different thing?

Ignore the existence if HFC 22. It's a real thing, but has never been used in airsoft. It's what people used to think green gas actually was. Turns out, as we all know, green gas is propane.
You want to use HFC 134a exclusively in that thing. Green gas/Propane/LOLHFC22 will tear it apart. Maruzen makes decent guns that can't last on propane for shit.

I don't think you understand. You don't want to use HFC 22. It would serve no purpose. It runs at a pressure similar to propane, and thus you would just use propane. However, you don't want to use propane. You want to use HFC 134a.

Correct me if I'm wrong, HFC 134a is duster gas correct?

Yes, with a caveat. Some duster gas is HFC 134a (1,1,1,2 Tetrafluoroethane), but some duster is HFC 152 (difluoroethane). Both chemicals have nearly identical pressure at temperature. The HFC 152 suffers a bit less from cool down and as such provides slightly more consistent performance. The difference is marginal but extant. If you have the choice, go with the difluoroethane. If you don't, buy whatever duster is cheapest/easiest to find.

I'd assume I need an adapter for this.

I don't understand why propane would tear it apart if it's the same as 134a. If you add the silicon oil aren't they exactly the same?

X, you're thinking of "green gas" not 134a.

For some reason I thought green gas = 134a. I don't really know why since I also know that its the same as propane and propane != 134a. What's the airsoft equivalent of 134a?

X,
134a is the airsoft equivalent of 134a. That's what they've always packaged and sold for Japanese guns. It was always just called "134a."

I guess I was thinking that there were three different levels, Green Gas (propane), Red Gas (?), and some other color or name for 134a.
