Alpenflow Fuel Transfer Valve

Alpenflow Fuel Transfer Valve revolutionizes backpacking fuel management by enabling safe, efficient transfer of isobutane between EN 417 threaded canisters, perfect for consolidating partials, topping off before trails, or sharing with partners. Weighing just 2.4g, this USA-made device uses simple pressure differentials. Warm canister on top, cool on bottom for spill-free liquid fuel flow without threads or complex setup.

Key Features

• Ultralight Design: Only 0.09 oz (2.4g) with reinforced nylon valve and NBR foam; fits any repair kit.
  
• No-Thread Simplicity: Stack canisters vertically and press down 5-10 seconds; repeat for full transfer.
  
• Pressure-Driven Transfer: Warms donor in sun (no flames); flow stops naturally when temperatures equalize.
  
• Universal Compatibility: Works with all standard isobutane backpacking stoves; ideal for winter mix fuels.
  
• Safe & Versatile: Consolidate hiker box finds, refill small cans from large, or split fuel; never overfill beyond 80%.
