3″ Cubic Mini Stove Adapter


This adapter gives you a proper connection from Cubic Mini flue flange or Cubic Mini’s double-wall pipe to a standard 3″ single-wall pipe.  It can be used to connect a Cubic Mini stove to our standard 3″ single-wall pipe, or to connect the top of Cubic Mini’s double-wall pipe to the single-to-double adapter in our 3″ roof installation kits.

Don’t forget clamps! Every pipe joint needs to be secured with either a clamp or three stovepipe screws. We recommend ordering a pipe clamp along with each section of flue pipe.

The Cubic Mini Grizzly and Cub have an oddly sized flue flange that is slightly smaller than a standard 3″ pipe. This adapter connects to the inside of the flue flange (or the Cubic Mini Pipe) then properly connects to our 3″ single-wall pipe pipe.

Cubic Mini’s stovepipe is non-insulated double-wall, so it’s not ideal for passing through combustibles.  To use our 3″ insulated pipe to install your Cubic Mini safely, you’ll need to adapt from the Cubic Mini flange to a standard 3″ size.  You can use this adapter to connect the Cubic Mini flange to the 3″ single-wall pipe in one of our 3″ roof exit kits, or use it to adapt the top of Cubic Mini’s double-wall pipe to our single-to-double adapter.

Made of carbon steel and painted with black high-temp paint.  A previous version of this part fit the Cubic Mini flue flange but not the Cubic Mini pipe.  The current version of our Cubic Mini adapter fits either one.

      Hi Kevin,

      The adapter is uniquely designed to fit both inside and outside the collar of a Cubic stove.
