The DuraVent PelletVent Pro Increaser is used to convert a 3" PelletVent Pro Pipe to 4" PelletVent Pro Pipe. The 3" side is a male pipe end and the 4" side is a female pipe end. Th is is used when a stove with a 3" diameter exhaust hole requires a 4" diameter vent pipe. Longer pipe runs and vent paths with multiple pipe bends oftentimes require the need to increase the pipe size. Make sure to look at the pellet stove manufacturers installation instructions to determine if you will need a 3 or 4 inch vent pipe. Available only in a galvalume outer finish. Show more
