Alpenflow Fuel Transfer Valve by Alpenglow Gear

Transfer fuel between canisters with a device that weighs less than a penny

The Alpenflow Fuel Transfer Valve is an ultralight little gadget that saves weight and waste. The Alpenflow was dreamt up by Alpenglow founder Tom ( a.k.a. "Gadget") along the Pacific Crest Trail after seeing piles of semi-filled fuel canisters in hiker boxes. Consolidate your stash, split fuel with friends, or score a free boost from a hiker box. It’s so light that even the gram counters will consider it worth its weight to bring.

How to Use

1. 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

2. Place warm canister on TOP, cool canister on BOTTOM (no threading needed)

3. Ensuring the stack is vertical & aligned, press down h ard for 5 - 10 seconds

4. 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.

Please read the instructions and safety warnings to understand the risks when using.
