DuraVent FasNSeal 15 Degree Elbow: a gentle sideways shift around an obstruction
The DuraVent FasNSeal 15 Degree Elbow is a stainless steel vent fitting that makes a small turn in the exhaust path. It makes the gentlest turn in the FasNSeal range. Two elbows let the run move sideways around a joist or pipe, then return to its original direction. That shallow bend offers little resistance to exhaust and helps keep condensed water from getting caught in the turn. The welded angle is fixed, not adjustable. 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 to match the vent run. A gasket and a built-in locking band at the wide end seal and secure the connection. Plan for open air between the vent and wood or other materials that can burn. The space needed depends on the appliance’s exhaust temperature. Keep that space free of insulation, and keep the vent from touching plumbing or wiring. Need double wall venting? See the DuraVent FasNSeal W2 15 Degree Elbow double wall fitting.
