Thread: refill your disposable canisters

I had the same problems, ended up warming the cylinder in the sun for a while, and putting cannisters in the freezer.. Worked well...

What's the secret to getting gas in? (I'm inverting the LPG bottle and can see the gas flowing).

Leave the gas bottle in sun or inside to warm up for 30 mins or more, and put the empty canister in the freezer for 5 mins before filling.

I can fill the canister to normal full weight no prob, you need to be careful not to overfill too much.

I bought two of those dodackies & neither will screw in properly, useless

Mine didnt either, i modified it using the screw in bit from an old regulator i had.

I don't understand why you would do this?
Surely the canisters are a mix of butane and propane to work at altitude, but you don't get that mix from LPG.

Yes you do, I believe that LPG has a even more favorable mix of the two, like 60/40

I couldn't tell any difference between a can of "high altitude" mix and a can I filled myself and used @ 1700mASL in the snow.

Do you have the donor cylinder "up side down"? You want to transfer liquid not gas.

You can get a mix from Filling Stations (not petrol stations) called propane plus!

Anyone got a link to a recommend filling adaptor?

Yes

so where do you get your hands on one of these? and maybe not a total cheap arse one but medium quality?

Look back through the thread, a few including myself have posted up links.
