DuraVent Model BV Oval Tee Cap: closes the tee bottom and comes off for inspection
The DuraVent Model BV Oval Tee Cap is a removable cover for the open bottom of an oval vent tee. It closes that opening to keep room air from leaking into the vent. You can take it off again when the inside needs a look. DuraVent calls for a cap on every open tee end, so an unused opening should not be left uncovered. Model BV is DuraVent’s Type B gas vent, the double wall pipe that carries the exhaust from a gas furnace, boiler, or water heater out of the house.
Choose a 4, 5, or 6 inch cap to match your oval tee. Oval Model BV has an aluminum inner pipe and a galvanized steel outer pipe, with an air space between the two. Plan to have a licensed installer handle the work with your local inspector. Need the tee this cap fits? See the DuraVent Model BV Oval Standard Tee fitting. The DuraVent Model BV Oval Tee Cap ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
