DuraVent introduces the only UL 1738 listed super-ferritic flexible gas vent component. FasNSeal® Flex, a flexible vent component, safely and efficiently provides superior venting for Categories II, III and IV gas burning appliances. Use FasNSeal® Flex when side wall venting is not an option and a crooked chimney offers the only way out. FasNSeal® Flex can only be used in vertical or near vertical runs of the system. FasNSeal® Flex is manufactured with precision engineered Sure-Seal locking seam, single strip, double layer of super-ferritic stainless steel which is scientifically proven to resist corrosion from toxic by-products of gas and propane fuels. FasNSeal® Flex’s unique construction provides for highly durable maneuverability and most importantly full appliance efficiency.
