FasNSeal®

    DuraVent FasNSeal single-wall and FasNSeal W2 double-wall AL29-4C is the original stainless steel special gas venting system developed by PROTECH. FasNSeal is approved for use on a wide variety of natural gas or propane Category II, III, and IV appliances or Canada’s Type BH Gas Vent Systems.

    All FasNSeal vent lengths and components feature a patented built-in mechanical locking band and triple-lipped directional gaskets for ease of installation. Available in diameters from 3″ up to 24″.

    With FasNSeal W2 double-wall, a ½” air space between the inner and outer walls helps to reduce clearance to combustibles and creates a heat shield for additional safety where MAN-SAFE policies may apply.

FasNSeal® Flex

    DuraVent FasNSeal Flex is made from super-ferritic stainless steel. It features a smooth inner-wall to optimize gas flow, minimize back-pressure, facilitate better condensate management, and to make cleaning easier. FasNSeal Flex is the only flexible chimney liner approved to both ULC-S636 and UL 1738. It also meets the UL 1777 standard.
