Propane/Butane

Havermeyer

It may be a stupid question, but I'll ask it anyway. I bought an airsoft gun which can take propane gas. Was just wondering would butane work in the same way? Or would it totally feck my gun up?

Cheers.

Butane will feck it up, so will a Propane/Butane mix, it needs to be pure Propane.

No Mate, butane or propane/butane mix wont work. Not a tech head so dont know why. It has to be pure propane. Propane is available in B&Q but you need a special adaptor like this one

Edit: Ach just beaten by Fiach

Cheers. Thanks for the advice chaps. I have one of those adaptors, just need the gas. :S

Butane will work, it's just considerably weaker so unless it's an NBB then your slide may not cycle complelely. I often use butane in the house for taking potshots in my living room as it's safer indoors (due to decreased power) and doesn't smell. The only other dis advantage I've found is that butane seems dryer than propane so you need to oil a little more often.

However, don't bother using it in a skirmish, far too weak.

There is another gas called Mapp in a yellow bottle
My father uses it all the time along with propane gas in his line of work.

He reckons that Mapps gas has the same pressure as propane with the only
difference being that it burns at a higher temperature

Dunno if it will work ok or damage a GBB. It shouldnt but maybe
peeps here know better. (when I mentioned it before people on these boards
did nto seem to thing it could be used)

Mapp gas doesn't work I tried it. The slide won't cycle fully and there are allot of jams. It sticks red rotten too.

Mapps, butane, butane/propane mix, all are crap for this purpose.

It's propane only I'm afraid.

I'm just sitting here reading the contents of a bottle of ultra air power gas bought from MIA (BFSL) is working tonight in a WE 1911 out doors. the ingredients are C3H8 (propane) and C4H10 (butane). this is working very well anyone care to shed some light ?

A chemist who studied the "ingredients" on those bottles posted on ASI once saying that apparently the ingredients are a load of lies because the molocules listed wouldnt chemically hold together.

Yeah and the guy who invented the propane adapter had commercial airsoft gasses tested in a lab too and they concluded that that the Airsoft gas companies were writing fairytales. Green gas is just propane mixed with a chemical perfume to mask the wack

for a minute there i doubted you, but i just took out a can of ultrair gas i have here and it's the same ingredients... how strange

i'd imagine the percentage mix between propane/butane in ultrair gas is different to that in the propane/butane mix they sell in b&q and the like though

oh and from wikipedia, "MAPP gas is liquefied petroleum gas (LPG) mixed with methylacetylene-propadiene." - petroleum based products will wear down o-rings and other seals in your gun/mag, so do not use MAPP

Fiach: given that he sells the propane adapter then it's not exactly an independent study, but all i know is, propane works fine for me

True enough, but he did put the lab results up and you can clearly see green and propane are identicle minus the chemical perfume and some atomized silicone in certain brands.

And God bless them for masking that stench. We have propane, we have silcone oil. Now all we need is some liquid febreeze to add a drop or two of to mask that horrible odour and we've replaced green gas for good.
