DuraVent DuraFlex Stainless Long Tee Snout: a longer branch for thick chimney walls
The DuraVent DuraFlex Stainless Long Tee Snout is a longer side branch for a tee at the bottom of the chimney. It reaches through a thick masonry wall when the standard branch cannot reach the connector pipe. It passes through the thimble, the sleeve through that wall, and twists into the tee body just like the removable branch it replaces. DuraFlex Stainless is DuraVent’s flexible stainless steel liner for relining a masonry chimney that vents a wood, pellet, oil, or gas appliance. Choose a 10 or 12 inch diameter for a custom length Pro liner.
The 304 and 316 liners stop at 8 inches. At the chimney top, these larger Pro sizes use a separate plate and a cap carrying its own rain collar, rather than a collar welded to the plate. Fittings grip the liner’s ridges with a built in band clamp, without drilling or riveting the liner. The connection to rigid pipe uses screws or rivets. Need the matching tee?

The DuraVent DuraFlex Stainless Long Tee Snout ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
