I’ve got a thousand loose isobutane canisters and I need the doohickey that will allow me to combine them.
Recos are all over the place. Some recommend the $35 flipfuel on GGG, but reviews there say it’s just another knockoff. Some of the Amazon specials may or may not support larger canisters. I see the campingmoon one recommended pretty widely, and it’s 11 bucks on AliExpress, so I’m leaning in that direction. Thoughts?
Also, is the Jetboil crunchit the best option for prepping my surplus cans to trash?
I think by this point, they are all knockoffs of some original design. There’s not a lot to them: Two tank connectors, a valve, and some have a pressure release button to bleed vapor off of the receiver canister.
If it were me, I would stick with the cheap option, with the understanding that there is a small chance the manufacturing quality might be so bad the cans won’t seal up. But probably it will be fine.
These don’t fully transfer fuel though, they equalize them right? You don’t end up with 1 full tank and one empty tank, but rather you end up with 2 half-full tanks.
@Ren
I think you are misunderstanding. I hope you are, anyway.
My understanding is that you can use these to fill partially empty cans by placing the receiving tank in the freezer and the transfer tank in warm water, and then allowing the gas to flow from the warm, full can into the cold, empty can.
@Jesse
Pretty much. If there’s liquid, it’ll transfer. Any vapor left isn’t really that much. I’ve added a little propane to the tank I want to empty to keep the pressure up.
Pure propane has a higher pressure than isobutane/propane blend, but isobutane blend at 100°F is about 125psi, roughly the same as propane at 75°F.
I’d not put pure propane in an isobutane can and take it anywhere, but a little to help transfer in a controlled environment isn’t a huge risk.
