The IMPERIAL MFG GROUP USA INC BM0152 is a 7-inch, 24-gauge black steel cleanout tee cap designed for single-wall black stovepipe and B-vent chimney connector systems. The crimp end allows the cap to slide snugly into the tee fitting, sealing the cleanout opening and preventing backdraft, debris intrusion, and heat loss. HVAC technicians and chimney installers use this cap to close the lower port of a tee during initial installation or when the cleanout is not in active use. The 24-gauge steel construction provides durability in flue applications where temperatures and soot deposits are a routine service consideration.
This cleanout tee cap is suited for residential and light-commercial venting installations using 7-inch black single-wall stovepipe or chimney connector assemblies. Common applications include wood-burning stove venting, pellet stove connectors, and oil or gas appliance flue runs where a tee with a cleanout port is part of the venting layout. The cap is sold in a package quantity of 12 units, making it a practical stocking item for contractors managing multiple installations or service calls.
Designed as an OEM-style replacement and standard fitment cap for 7-inch black single-wall stovepipe tee fittings used in residential and light-commercial venting connector systems.
Installation is performed by licensed HVAC technicians or qualified chimney service professionals in accordance with NFPA 211 and local mechanical codes. Allow the flue system to cool completely before handling or replacing the tee cap. Insert the crimp end into the cleanout opening of the tee until the cap seats fully. Inspect the surrounding tee fitting and connector sections for creosote buildup or damage during any service that requires cap removal.
