6-In X 8-In Black Steel Stove Pipe Increaser

This Imperial 6-in x 8-in increaser is an ideal solution for connecting smaller-diameter stove pipe, fittings or flue outlets with larger-diameter stove pipe, fittings or chimneys. The larger end of the increaser is crimped to allow for making easy connections to 7-in round pipe or fitting openings. It is constructed with 24-gauge cold-rolled steel and finished with a black matt paint that resists chips and scratches for long-term performance and durability. The stove pipe increaser has a maximum temperature rating of 700°F, with a short-term exposure rating up to 800°F.
