Efficient fuel management in a tiny package.
Alpenglow Gear says:
The Alpenflow is an ultralight transfer valve for fuel conisters, usable in the backcountry or at home.
You can power the transfer with sunshine or a refrigerator, regardless of fuel level. Manage your fuel reserves, take from partial canisters, or divide a larger canister among friends!
Instructions:
- Warm Your Donor Canister and/or Cool Your Recipient Canister
- This transfer requires a pressure difference to push the upper liquid fuel down into the lower canister.
- The donor canister can be warmed in the sun, never use an oven or flame
- The larger the temperature difference, the faster the transfer will occur - Place Warm Canister on TOP, Cool Canister on BOTTOM (no threading needed)
- Ensuring the Stack is Vertical & Aligned, Press Down Hard for 5 - 10 seconds
- Repeat as Needed, especially if filling a near-empty lower canister.
-Once the warm donor fuel mixes & warms the lower liquid fuel sufficiently, the transfer will slow & eventually stop.
Warnings & Safety:
- To mitigate the risk of liquid butane expanding when canister is heated, never fill beyond the original fill level (~80%)
- Fuel canisters do not meet D.O.T. requirements for commercial transportation after refilling (a.k.a. it’s illegal for businesses to transport refilled canisters)
- Never use a flame or oven to heat canisters
- Never fill canisters with pure propane, and only transfer “winter mix” fuel (70% butane / 30% propane) into canisters rated for winter mix fuel.
Our Verdict
At only 2.4g, the Alpenflow Gas Transfer Adapter is one of the lightest pieces of kit in my pack. It connects canisters and allows for liquid fuel transfer with little effort. The process is straightforward, making it easy to consolidate the numerous canisters I have lying around. This helps save weight, and means im not wasting gas. It's a handy gadget to bring on trail, too, as you will often find half-used gas canisters in trail towns, bothies, and youth hostels you can top up from.
I recommend watching the video listed above for full instructions on how best to use the device.
