6'' to 8'' DSP Double Wall Increaser - DSP-I68

Our DSP Increaser is used when an installation calls for the need to increase the size of the pipe to make a connection between a 6" and 8" piece of pipe. It's constructed with a 26 gauge steel outer wall and a corrosion resistant, 400 stainless steel inner liner. The double wall construction reduces clearances to combustible materials down to 6", and allows a 1/4" air space between the inner and outer pipes to provide superior insulating value to accommodate higher flue gas temperatures, while creating an outer shell that remains cool to the touch. The Increaser is coated in a scratch resistant, black enameled paint to ensure a flawless, finished look.
