Fuel Transfer Valves for Backpacking: Fuel Physics, Myths, Risks, and Real-World Performance

This article examines canister fuel transfer devices from a thermodynamics and engineering perspective, focusing on pressure-driven flow, headspace constraints, fractional distillation of LPG mixtures, and measured transfer rates. It evaluates Alpenflow, FlipFuel, and generic EN 417 adapters and outlines conservative operating practices that respect established EN 417 design safety margins.
