HFC 134a alternative

[Kingsix]

Hey guys,

I recently got a Japanese Marushin revolver and was wondering if there is an alternative to HFC-134A known as gun gas in Japan.

Some people have told me to just use regular Green-gas but I am worried about premature wear due to the higher pressure.

Although the Marui's are strengthened to some degree to use green gas other companies like Tanaka, Marushin, etc do not.

I used to be able to buy them from electronic supply stores as circuit board cooling gas but it seems the EPA has deemed it a green house gas and has banned it in 2015. I know the EPA is a American Agency but Canada follows EPA trends pretty closely.

Using normal computer duster is questionable, the added bitterant agent is sticky and likes to gum up valves over time so it's a no go for me.

I've been running my Marushin's on green gas for quite a while now, no issues at all. They're surprisingly tougher than Marui revolvers, I've seen more Marui revolvers with issues running green gas than Marushin's.

That said, some Marushin may need a tiny bit of work to get it to run reliably on green gas. A number of the ones I've seen have been sitting for a while and tend to leak right out of the box. Had that issue w/ my SAA when I got her and after a bit of maintenance she runs great on green gas. I usually tear them down for a maintenance check every couple of months, but haven't ran into any big issues yet.

Out of curiosity, which Marushin wheelgun did you pick up?

Hi Beta,

I will check tomorrow when I get some green gas. Not going to run propane until I think she can take it.



Marushin New Nambu M60 3" 6mm Heavy Weight Version, I was split on this or a Tanaka M36 J Police or HWS Hartford Type 26, HFC M10.

Green gas is propane.

Just use duster gas from Costco.

I am aware green gas is propane, I think the canned stuff is at a local pressure than the camping tanks.

None the less I'll have to check out Costco, in case my research is wrong. Might go check Sayal to see if canada has banned HFC-134A or it's just an American thing.

Sayal has them, but it's $16-20 a can unless you buy in bulk.

¯\_(ツ)_/¯"

I thought this thread was about an M134. Sad now

Very nice! Quite tempting to add that one to my ever growing collection as well. The Marushin's are surprisingly nice, probably the most prized guns in my current collection (until I find a Tanaka SAA and a metal kit).



Both the SAA and M36 haven't had any issues w/ green gas ever since I've gone over them. As long as they're well maintained, I don't foresee much trouble with continued green gas usage.
