I need to replace an 8' section of 4" flexible ducting. Had mice nest inside and they had chewed holes in it. Sticker on ducting says Type 1 Air Connector plus other specs re velocity and pressure. for a Google search: "Class 1 represents a material which shall have a flame spread rating of not over 25 without evidence of continued progressive combustion and a smoke-developed rating of not over 50."
I can't find a hose that specifically states a "Class 1.

- Any idea where to obtain OEM Class 1 ducting?
- Can a dryer vent hose be used? It looks the same but I'm leery because the ducting snakes around and through and underneath cabinets, stove, near converter, etc...
