DuraVent FasNSeal Chimney Kits

DuraVent FasNSeal® single-wall vent pipe and components feature a patented built-in mechanical locking band and triple-lipped directional gaskets for fast, secure installation. Smooth welds sit 90° from the locking band for easier assembly. FasNSeal® W2 adds a ½" air space that reduces clearance to combustibles and acts as a heat shield.
