DuraVent DuraFlex Stainless Tee with Cap: connects the liner to stovepipe through the chimney wall
The DuraVent DuraFlex Stainless Tee with Cap is a bottom fitting for a liner that connects to an appliance through the chimney’s side wall. Its built in band clamps the body to the flexible liner. The removable side branch twists into the body and locks, reaching through the wall opening to the stovepipe. A chimney sweep opens the bottom cap to clean the liner. DuraFlex Stainless is DuraVent’s flexible stainless steel liner for relining a masonry chimney that vents a wood, pellet, oil, or gas appliance.
Before relining, the chimney needs cleaning and inspection, with loose bricks or worn mortar repaired. The tee attaches before the liner is lowered from the chimney top. Its branch is then pushed outward through the wall opening. Choose a diameter to match your liner: 3, 4, 5, 5 1/2, 6, 7, or 8 inch. Note that the 5 1/2 inch tee has a 6 inch branch. Need a collar to line that wall opening? See the DuraVent DuraFlex Stainless Mortar Sleeve wall collar. The DuraVent DuraFlex Stainless Tee with Cap ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
