DuraVent FasNSeal Single Wall Adapter: changes W2 double wall pipe to single wall pipe
The DuraVent FasNSeal Single Wall Adapter is the adapter that joins a FasNSeal W2 double wall vent to single wall FasNSeal pipe. It makes that change in one direction, from W2 to single wall. FasNSeal W2 is DuraVent’s double wall stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, with an air space between its two walls. That 1/2 inch air space helps shield heat and reduces the space needed between the vent and nearby materials that can burn.
Choose your vent size on this page, from 3 to 16 inch. These sizes measure the inside of the vent, not its outer wall. An experienced professional fits the FasNSeal parts together. W2 connections use a gasket to seal the joint and a built in locking band to hold it together, just as single wall connections do. Changing from single wall to W2 instead? See the DuraVent FasNSeal Double Wall Adapter. The DuraVent FasNSeal Single Wall Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
