DuraVent FasNSeal Universal Appliance Adapter: connects more listed appliances than any other FasNSeal adapter
The DuraVent FasNSeal Universal Appliance Adapter is an adapter that joins a FasNSeal vent to an appliance’s exhaust outlet. DuraVent lists it for more appliances than its other adapters. It slides over the flue collar, the rim of that outlet, and locks with its own built in band. Listed appliance brands include A.O. Smith, Bosch, Lochinvar, Noritz, Raypak, Rheem, Takagi, and Viessmann. FasNSeal is DuraVent’s stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, built to carry pressurized exhaust and its acidic condensate outside.
Choose a size from 3 to 16 inch on this page, covering every FasNSeal size. The size measures the inside diameter and should match the appliance’s exhaust outlet. Your appliance maker determines which vent it accepts and how it connects, so “universal” does not mean it fits every appliance. Need a test port?

The DuraVent FasNSeal Universal Appliance Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
