DuraVent DuraFlex Stainless Tee Cap: removable cleaning access below a large tee
The DuraVent DuraFlex Stainless Tee Cap is a removable cap for the bottom of a 10 or 12 inch tee. The tee is the fitting at the lower end of the chimney liner. A band secures the cap to the tee body. Removing it lets a chimney sweep reach the liner from below for brushing and inspection. DuraFlex Stainless is DuraVent’s flexible stainless steel liner for relining a masonry chimney that vents a wood, pellet, oil, or gas appliance. Choose the 10 or 12 inch size to match your tee. The smaller tees already include their caps.
These larger sizes fit Pro liners, which are ordered in custom lengths at these diameters. The 304 and 316 liners stop at 8 inches. DuraVent recommends checking for soot or wood smoke deposits every two months during heating season and inspecting annually. Cleaning uses a polypropylene plastic brush on fiberglass rods, with access through this bottom opening or from above. Need the matching tee?

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