DuraVent FasNSeal W2 30 Degree Elbow: a double wall bend for routing around beams and ducts
The DuraVent FasNSeal W2 30 Degree Elbow is a double wall vent fitting that turns the exhaust path around an obstacle. Two elbows with a straight length between them let the run step sideways around a beam or duct. This makes a moderate offset, rather than a sharp turn. Each elbow is welded at a fixed 30 degree angle and cannot be adjusted. 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 3 to 16 inch size on this page to match the vent run. That size measures the inside passage. The outer wall adds 1 inch to the outside diameter, so it needs room too. A 1/2 inch air space helps shield heat and reduce the space needed from nearby wood framing. DuraVent designs FasNSeal W2 for routes inside walls or between floor joists, as well as commercial buildings. An experienced professional fits the run using FasNSeal parts throughout.
