If your MSR Dragonfly Stove has old or lost O-Rings, here is the replacement set.  If the O-Rings are gone, it can result in a fire starting other than at the burner. Yikes!

 

The bottom row of seals (in the picture) are ALL the O-Rings you would normally get if you bought the 29.95 MSR Service Kit from REI or so forth.  The upper rows of seals is what I sell.  As you can see, the sizes are a good match at a MUCH better price.  The color of the O-Ring does not matter in this case - the MSR Kit and my kit are all Buna-N.

 

O Ring Specifications:

Sizes Vary 

The O-Ring is Buna-N material (OEM spec). 

FREE SHIPPING anywhere in the continental U.S.  Shipping to Canada is 1.65.  Buy as many as you want.  The kit I sell contains two of each O-Ring - and I also throw in an extra ONE of each size. 

It is a bummer to break an O-Ring while out camping... been there, done that.  Be safe - please buy these and save yourself some serious trouble.  :)
