DuraVent FasNSeal W2 15 Degree Elbow: a gentle turn around an obstruction
The DuraVent FasNSeal W2 15 Degree Elbow is a double wall stainless steel vent fitting that makes a small change in direction. Two elbows together let a run step around an obstruction. This is the gentlest W2 turn, keeping resistance to the exhaust low and reducing the chance of acidic liquid collecting at the bend. The welded angle stays fixed at 15 degrees rather than adjusting. 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 3 to 16 inch on this page to match the planned vent run. The elbow joins the pipe with a gasket and a locking band built into the wider end. Each connection takes up 2 inches of length, which matters when planning the offset. W2 pipe cannot be shortened by cutting it on site. An adjustable length handles the extra inches needed to fit the route. Need the single wall fitting? See the DuraVent FasNSeal 15 Degree Elbow, the single wall version. The DuraVent FasNSeal W2 15 Degree Elbow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
