Hart Cooley 7rtc 7 Inch B-vent Round Tee Cap

Product Description

The HART COOLEY 7rtc is a round tee cap designed for use with 7-inch Type B gas vent systems. It seals the open end of a B-vent tee fitting, preventing backdrafts, debris entry, and moisture intrusion into the venting assembly. Weighing 1 pound, this cap is a standard service and installation component used by licensed HVAC technicians and gas appliance installers working on natural gas and propane appliance venting. It is appropriate for new installations and replacement service on existing B-vent systems.

This tee cap fits 7-inch round B-vent tee fittings and is used in residential and light commercial gas appliance venting systems. Typical applications include vertical vent risers with tee cleanout access points on furnaces, boilers, and water heaters vented with Type B double-wall vent pipe. The cap is installed at any tee opening not connected to an active vent run or appliance outlet.
