Next you need to cut a slot in the plunger to allow the gas to escape around the plunger. I used a jewelers saw. Outdoor or Camping Stores: Stores like REI, Bass Pro Shops, or local camping supply stores usually offer a variety of options and the added benefit of knowledgeable staff. While you can overfill the bottom canister beyond the amount of fuel that it originally held, I’d advise against doing this for safety reasons. You can measure the amount of fuel transferred by weighing the canister before and during the process so you know when to stop.

I make a disclaimer now. You must remember that these connections effect a gas seal with the o ring fitted in the female fittings, so you must ensure that you don't compromise this seal by damaging either the o ring or the blue plastic clamping mechanism. Below is how I did it.... Finally, the stove set up (e.g. stove model, windshield, heat reflector, heat exchangers on the pots) is a much bigger factor than the canister type.Most of these gas canisters have the EN 417 Lindal connectors, however three on the right do not. These are the large propane canister and the two Campingaz canisters, each with a different connector type- Easy Clic and bayonet type

Hardware Stores: Larger hardware stores like Home Depot or Lowe’s can also carry a range of adapters. Propane will boil to a gas at temps as low as -44°F, but butane is good only down to 31°F. In freezing temps, a canister will burn off the propane and isobutene first and the butane just sits in the canister as a liquid. Many Boy Scout troops see this in winter camping when using the two burner “Colman” type stoves with the green fuel bottles and the stove stops working because the valve froze up. Well it didn’t freeze up, the propane is just been burnt off. Use a propane tank from a home grill and the stove will work all day, and night, long till the propane tank is empty.This guide gives a simple explanation of the different types of camping gas available, which one you need for your camping stove and where you can find them. Some people seem to think that certain brands give a more consistent flow and let you use the full canister better. But that’s not widely experienced, there’s no obvious consistency in which are the best/worst brands, and I don’t know of any reason that would be true (ultimately, they are just metal pots filled with gas). Based on my testing, my advice would be to only use an inverted canister stove with refilled canisters to ensure that you can use all of the gas in the canister. The Kovea Spider can burn fuel from a canister oriented in either direction. I think inverted canister stoves like it are the best way to ensure you can use the entire canister contents when camping with refilled fuel canisters. The Kovea Spider stove can burn liquid fuel from a canister that’s been turned upside down. Inspect Material Quality – Look for adapters made from durable materials like stainless steel or brass, which are less likely to corrode or break.

The G-Works Gas Saverplugs into gas canisters using what’s called a Lindal valve. This is a standard canister attachment system that is used universally on canister stoves (in the US, but not Europe) to ensure that canisters from different manufacturers can interoperate with other manufacturers’ stoves. For example, it’s the reason you can use Jetboil, MSR, or Primus isobutane fuel canisters with a Snow Peak canister stove. You can also raise the pressure inside the upper canister, by raising its temperature. For example, plunge the upper canister into a bowl of hot water for a few minutes before attaching it to the Gas Saver. This is useful to speed things up and when the bottom canister has more gas in it than an upper, mostly drained canister. The actual speed of the transfer depends on the amount of the pressure gradient, but figure about 15-20 minutes to fill a small empty canister from a large, mostly full canister. The process is not terribly fast.What follows is not a recommendation. Three Points of the Compass is only commenting on what there is out there, products that some people have used and others do not. Products that seemingly no stove manufacturer other than those in Japan and Kovea countenance.

Return Policy– Especially when buying online, ensure there is a fair return policy in case the adapter is not compatible or meets below-standard quality.However, if you’re travelling through different countries or out in the middle of nowhere, you can’t always find screw-on gas canisters.
