Alpenflow Fuel Transfer Valve
Couldn't load pickup availability
This is the world's lightest tool to transfer fuel between canisters! You can split larger canisters at home, siphon from half-full canisters, or even drain a canister before recycling-- all for 3.1 grams (0.11 oz).
By creating a temperature difference between the canisters, liquid fuel will flow from the donor (on top) to the colder recipient (on bottom).
Saturn Revision: This updated version includes feedback from thousands of trail miles: instructions, a lanyard loop, and a wider outline are all now baked into the body so it's easier to use, keep, and find.
Tips & warnings:
- Never use a stove, oven, or flame to heat the donor can. Warming the donor canister should only be performed if cooling off the recipient isn’t possible.
- Only transfer butane, isobutane, or a winter blend (up to 20% propane)
- Never fill past the original canister's fill level (~85%)
- Please wait 30-60 seconds between applications to allow the foam seals to thaw and rebound. Immediately transferring without pause can lead to torn and permanently crushed seals.
- Fuel canisters are illegal to fly with even if empty
- For personal use only: USDOT 49 CFR §178.65 bans the transportation of refilled disposable canisters for commercial purposes in the United States

Ohhhh, so good, so so goooood... let's exchange fluids.... ooh baby! SO GOOD!
Easy to use. Ultra supreme maximim light weight
Works great! Easy to consolidate the leftovers in almost empty canisters.
Excellent customer service and answering all of my questions. Awesome ultralight products.
Excellent service and excellent product. I wasn't aware of this company but now look for them.
The Fuel Transfer Valve was shipped fast! Super light and looking forward to using it on trail. Also, fast shipping, minimal packaging!
The fuel value was so easy to use, and I love how small and light it is. Very happy with the product.
Works just as described. Cheaper than the alternatives, and light enough I can bring along!
Super small, cute, and works great!
Ordered the two-pack of these and have played with it at home, filling an empty canister from a less-empty one. The process proceeded very slowly at first, as the empty canister initially reached equilibrium after just a few seconds. But after the heating/cooling steps were repeated a few times, I was eventually able to refill the empty and it is good to go. So easy, so light, so ingenious! Strong work and simpler to use than some of the other products on the market.
I've used it once and it worked well. I did find the small amount of fuel spray a bit disconcerting. But it quickly stopped and the fuel transferred as expected. My 4oz canister went from 120gm to 200gm - basically from empty to full. I highly recommend reading the included instructions and watching the video as it operates differently than the other transfer devices on the market.
Works great
works great would buy again. shipping was on time
Handy little gadget! I successfully consolidated 3 cans of fuel into 1. Easy to use and takes up very minimal space in my gear box.
Ultra Responsive on DM's. Quick shipping and works like a charm.
