The perfect packable cook kit—why I transfer gas between canisters
One of the things I love about the 900 mL MSR Titan Kettle is how neatly everything packs together. A 227 g MSR isobutane canister fits perfectly inside the kettle, protected by the built-in silicone support, creating a compact, rattle-free cooking kit for backpacking, hiking, bikepacking and kayak trips.
The problem is that a 230 g Primus canister, although almost identical, is just 4 mm larger in diameter at the base. Those 4 millimetres are enough to stop it fitting inside the kettle.
Rather than carrying a partly used canister that doesn’t pack properly, I use a CampingMoon gas transfer valve to transfer the remaining fuel into an MSR canister. The process is simple: cool the receiving canister, gently warm the donor canister, connect them with the valve, and let the pressure difference do the work.
In this video I show:
* Why the Primus canister doesn’t fit the 900 mL MSR Titan Kettle.
* How the CampingMoon transfer valve works.
* How to transfer fuel using the pressure difference between a warm and a cold canister.
* How to keep your cook kit compact by consolidating partly used canisters.
⚠️ Safety: Fuel transfers should only be carried out outdoors or in a very well-ventilated area, away from flames, sparks and other ignition sources. Always inspect your equipment for leaks and follow the manufacturer’s instructions.
If you’re into ultralight backpacking, camping, bushcraft, canoeing, kayaking or long-distance hiking, this little trick can help you save space, reduce waste and keep your cook kit organised.
