DuraFlex 316 & 304
DuraFlex 304 and 316 are lighter, more economical liners. Excellent
when there are minimal osets in the chimney. DuraFlex 304SS and
316SS are intended for wood burning, non-condensing gas and oil
red appliances. Where greater corrosion resistance is desired, such
as coal-red appliances, DuraFlex 316 is recommended. DuraFlex
304SS and 316SS are listed to UL 1777 and ULC S635.
