while trying to find Rep Orings I found this.

been going crazy looking for Orings for my fire luke mesh pro and I found this product

ADV Kit - MESH Pro - Freemax

not only do they have replacement Orings (various colors) but they also have a kit that will expand the tank to hold 13ml of the good stuff. I have ordered one of these kits and am super excited.

I received the kit 2day and installation was no problem. doing the leak tests now so far no problems of any kind.
flavor is the same just got me a whole lot more capacity.
