DuraVent FasNSeal Weil McLain Tee Appliance Adapter: connects a FasNSeal vent to listed GV Gold boilers
The DuraVent FasNSeal Weil McLain Tee Appliance Adapter is a tee shaped part that connects a FasNSeal vent to a boiler’s flue outlet, the opening where exhaust leaves the boiler. DuraVent lists this 3 inch adapter for Weil McLain GV Gold Series 3 and Series 4 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.
An appliance outlet is not always made to accept FasNSeal directly. DuraVent offers appliance adapters to make that connection for many appliances, with this one listed for the boilers named above. The 3 inch size measures the inside diameter and should match the appliance’s flue outlet. Looking for the GV Series adapter instead?

The DuraVent FasNSeal Weil McLain Tee Appliance Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
