I first bought a MSR Fuel Bottle (325 ml, aluminum) for packing denatured alcohol for my Trangia stove. Hiked with it for over a year with no leaks (safety-lock cap) or issues. Just bought a Trangia Fuel Bottle (300 ml, polythene) with push-button cap for dispensing fuel. Both high quality bottles. Discovered that the caps for each bottle thread into the other product bottle, no problem. Though the O-rings and cap lip are slightly different sizes, the Trangia dispensing cap easily threads and seals into the MSR bottle. The MSR safety-lock cap does thread into the Trangia bottle, however, the safety-lock cap does not completely seal on the Trangia bottle due to the (larger) metal reinforcing ring on the Trangia bottle preventing the cap from fully seating. I also tried the MSR Expedition Fuel Bottle Cap (non-safety cap) and that sealed on the Trangia bottle, but the cap lip and O-ring size were slightly larger than those of the original Trangia dispensing cap. I have not field tested the Trangia dispensing cap on the MSR bottle, but in a 15-minute inverted position leak-test there were no signs of fuel leakage from the thread/cap area. The Warning on the Trangia bottle warns "Don't pressurize the bottle." The MSR bottle advises "Contents under pressure."
