DuraVent FasNSeal 90 Degree Elbow: a fixed square turn for your vent run
The DuraVent FasNSeal 90 Degree Elbow is a stainless steel vent fitting that turns a run from sideways to upright, or the other way around. Its welded bend stays at 90 degrees and cannot be adjusted. Of DuraVent’s elbows, this turn puts the most resistance in the exhaust’s path, so the appliance maker’s allowance for elbows matters when planning the run. FasNSeal is DuraVent’s stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, built to carry pressurized exhaust and its acidic condensate outside.
Choose a 3 to 16 inch size on this page, measured across the inside of the vent to match the appliance outlet. A gasket and a built in locking band sit at the fitting’s wider end to seal and hold the connection. Each joint takes up 2 inches of pipe length, which matters when figuring how much room the finished run needs. Need the double wall version?
