Does anyone know what non-Optimus fuel bottle will work with the Nova + stove?
I always recommend using the same brand fuel bottles. Primus bottles will work but the threads between the two are slightly different which could possibly become a fire hazard due to escaping fumes & loss of pressure. Go with the Optimus bottle just to be safe. The risks are simply not worth the potential consequences!
The fuel bottles are all pretty standard. I use a small MSR fuel bottle with mine, because the store only carried MSR bottles and I needed a small one.
Mine works fine with an MSR fuel bottle, though I mainly use the Optimus fuel bottle.
The wider shape of the optimus bottle probably makes the air purge feature work better than a narrower bottle, at least when it's full, but this isn't critical.
