DuraVent FasNSeal Metric Male Appliance Adapter: connects metric boiler outlets to inch sized vent
The DuraVent FasNSeal Metric Male Appliance Adapter is an adapter that joins a boiler’s metric exhaust outlet to inch sized FasNSeal vent. Each size is listed for specific boilers. 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. The 149 mm adapter connects to 6 inch vent for De Dietrich C-230 ECO. The 158 mm connects to 6 inch for Buderus GB312 90 to 160. The 197 mm connects to 8 inch for Buderus GB312 200 to 280. The 250 mm connects to 10 inch for De Dietrich C-130 ECO and C-310, and Patterson Kelley C1500 and C2000.
Choose 149, 158, 197, or 250 mm on this page to match the listed boiler. The entire vent path to the outdoors uses FasNSeal parts. Other brands’ pipe, fittings, and connection methods must not be mixed in because their joints seal differently. Looking for the GT Series adapter?
