DuraVent FasNSeal IPS Drain Fitting: a threaded drain connection for iron pipe
The DuraVent FasNSeal IPS Drain Fitting is a stainless steel drain fitting that connects to a tee in the vent run. It has a 1 inch threaded pipe connection rather than a hose stub. That lets iron drain pipe carry the acidic liquid to a neutralizing tank, where it is treated before entering the sewer. This is DuraVent’s drain style for vents larger than 5 inch. 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. It serves natural gas or propane appliances that call for a special gas vent.
Choose your fitting size on this page, from 3 to 16 inch. An experienced professional handles the vent installation, and DuraVent recommends a yearly check of the entire run by a qualified inspector.

The DuraVent FasNSeal IPS Drain Fitting ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
