Great fuel cap...simple and effective.


  • Simple, nothing to break
  • Lightweight
  • Seals well


  • doesn't pour well

This is the stripped-down fuel cap for MSR bottles. It's lighter than the child-proof cap, without any mechanism to break.

It does have a tiny bill one side meant to be used to pour fuel, but I would only use it for that purpose in an desperate situation. It doesn't produce a clean, neat stream. So, it's difficult not to spill fuel. The best use is simply sealing you fuel bottle when the pump is not in use, which it does very well.

I have used one of these caps for over 10 years and it's still going strong without ever having a leak. The O-ring that seals the bottle is also replaceable if it degrades.  


Thanks for sharing a review of this cap, Justin. Often the small accessories that make a difference get overlooked. Got any pictures of yours to show others in your review?
