DuraVent FasNSeal Horizontal Drip Tee: a drain beneath a horizontal vent run
The DuraVent FasNSeal Horizontal Drip Tee is a short stainless steel tee that drains liquid from a horizontal vent run. A small connection underneath lets condensate, the liquid that collects from the exhaust, be piped away. The fitting sits with that connection pointing straight down. DuraVent’s vent drawings place it near the appliance, so it provides a drain point at that end of the run. 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 the 3 inch or 4 inch size on this page to match the planned vent run. This is a single wall fitting, with stainless steel inside and out and welded seams. An experienced professional handles the installation, and DuraVent calls for a qualified inspector to check the entire run each year. Need a drain for a larger vent? See the DuraVent FasNSeal Horizontal Drain Fitting for larger sizes. The DuraVent FasNSeal Horizontal Drip Tee ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
