MSR 3-in-1 Cap

— Show original

A good replacement cap if you have an older version of MSR water heaters, where the cap has a separate drain cap with a smaller mouth opening. Here, the mouth opening is the size of a PET bottle cap, i.e. the cap in soda bottles has the same thread and size. In addition, this has a small swivel nozzle, from which you can pour water more slowly if you need, for example, a tablespoon, etc. The cap has the same size and thread as, for example, Nalgene bottles 1 L and larger. And also in Ortlieb water heaters, i.e. also suitable for them. The difference with Ortlieb's cork is that this one has a shorter length for the PET thread plug, because of that Ortlieb's natural hose adapter tends to leak a little if you don't put a seal in between.

I bought 2 pcs to replace the broken ones. Leaks annoyingly a little in old (<2010??) MSR DromedaryBags, the dimensioning of the sealing groove of the big cap has changed just that much. The grip roughness of the big cap is also worse than in the old ones, I noticed when I tried to make the cap tight.
