3″ Insulated Stainless-Steel Flue Pipe

High quality 3″ double-walled Insulated stainless-steel flue pipe. This pipe is ideal for transitioning through roofs or walls as the insulation gives it much narrower clearances (2″) to combustibles. Pipe comes in 20” & 40” lengths. You will need a single wall to double wall adapter to connect this to single wall pipe.  Use our flue parts calculator to figure out exactly how much pipe you need for your project.
