DuraVent FasNSeal W2 Wide Mouth Boot Tee: a gentler turn from horizontal to vertical
The DuraVent FasNSeal W2 Wide Mouth Boot Tee is a double wall stainless steel fitting that turns a vent run from sideways to upward. Its widened, sloping passage gives exhaust a more gradual turn with less resistance than a square tee. It can also serve as a manifold, the connection where several boilers feed one vent, when the boiler maker approves that arrangement. FasNSeal W2 is DuraVent’s double wall stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, with an air space between its two walls.
Choose a size from 4 to 16 inches on this page. The tee has fully welded inner walls and accepts a tee cap. It serves natural gas or propane appliances that call for a special gas vent. The appliance maker determines the allowed length and direction of the run, so the tee needs to fit that plan. Need the single wall version?
