DuraVent FSTB4 FasNSeal 4 Inch Diameter Single Wall and Double Wall Interchangeable (300501)

FasNSeal is a Special Gas Vent and Gas Vent Connector, made from AL29-4C stainless steel and designed for use on natural gas or propane-fired appliances listed as Category II, III and IV or in Canada Type BH Gas Vent Systems having a rated operating temperature of 480 degrees F and maximum positive pressure of 6" water column. FasNSeal provides horizontal or vertical venting for high efficiency gas boilers, furnaces, booster heaters, pool heaters, water heaters, unit heaters or tankless water heaters. FasNSeal may also be used as a vent for Category I, natural gas or propane-fired heaters. FasNSeal must be sized according to the heating appliance manufacturer's instructions, NFPA 211, NFPA 54 and any other relevant local building codes and regulations (see installation instructions for details).


Each vent length and component features a built-in mechanical locking band and gasket. Parts are simply pushed together to a stop bead, which renders the joints air and water- tight. By tightening the integrated mechanical locking band, parts are fastened together in seconds. FasNSeal can be taken apart and reassembled in minutes, making inspection, maintenance or rerouting of FasNSeal systems a breeze. Should a part or gasket ever become damaged, replacement takes less than five minutes and the integrity of the system is not compromised! Connecting FasNSeal to a heater is done efficiently with one of our many adaptors approved by heating appliance manufacturers. Heating equipment can be fired up immediately upon completing a FasNSeal installation, as no cure time or cleanup is required. FasNSeal features a smooth weld seam inside and out, which is completely shielded during the TIG welding process. Contamination or molecular changes in the weld seam are avoided; no fillers are used in the welding process.

FasNSeal is manufactured from AL29-4C, a superferritic stainless steel designed for extreme resistance to chloride ion pitting, crevice corrosion and stress corrosion cracking, as well as general corrosion in oxidizing and moderately reducing environments. AL29-4C is an ideal choice for resisting deleterious effects of corrosive condensates created by partially or fully condensing natural gas and propane fired heating appliances. FasNSeal has been tested and is listed by Underwriters Laboratories, Inc. to UL 1738 and ULC-S636-95.
