DuraVent FasNSeal W2 45 Degree Elbow: a gentler turn for moving the vent around an obstruction
The DuraVent FasNSeal W2 45 Degree Elbow is a double wall stainless steel fitting that changes the vent’s direction. Two elbows let a run shift around an obstruction and return to its original direction. One can also connect to the angled branch of a wye, a Y shaped fitting. The gentler bend puts less resistance on the exhaust than a square turn. It is welded at a fixed angle, so it 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 size from 3 to 16 inch on this page. This elbow serves natural gas or propane appliances approved for a special gas vent, including tankless water heaters and unit heaters. The appliance maker determines the allowed vent length and route, so the elbow needs to fit that plan. Need the single wall fitting? See the DuraVent FasNSeal 45 Degree Elbow, the single wall version. The DuraVent FasNSeal W2 45 Degree Elbow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
