Dura/Connect II is now UL approved as a Type B gas vent segment for use in attics and crawl spaces, according to Simpson Dura Vent.

The double wall flexible vent is now certified as having the equivalent thermal properties as Type B gas vent, according to the company, and can be used when a B-vent double wall connector is required. Additional gas venting products include Type B gas vent, Dura/Connect, single wall connector and the DuraFlex flexible gas masonry reline system. Dura/Connect and Dura/Connect II can be used to connect single or multiple appliances to venting, provided the connectors and vents are properly sized.
