DuraVent Model BV 90 Degree Adjustable Elbow: a right angle turn with a base that rotates
The DuraVent Model BV 90 Degree Adjustable Elbow is a vent fitting for a right angle turn. It takes the pipe from sideways to upright. Two elbows can route it around an obstruction, with support above and below that detour. The 90 degree bend stays fixed while the base turns a full circle to line up. Choose a diameter from 3 to 8 inch. Model BV is DuraVent’s Type B gas vent, the double wall pipe that carries the exhaust from a gas furnace, boiler, or water heater out of the house.
Pipe and fittings stay uncut. Sections come in 6 to 60 inch lengths, and an adjustable length fills the remaining gap. A draft hood connector starts the vent at the appliance’s exhaust opening. It also joins single wall pipe to double wall vent. Single wall pipe stays in the open room, never through a ceiling. DuraConnect flexible connectors handle that connection without elbows or short pipe sections. Need a gentler turn? See the DuraVent Model BV 45 and 60 Degree Adjustable Elbow. The DuraVent Model BV 90 Degree Adjustable Elbow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
