Gas Fireplace

in THE MAIN WALL
I want to take out the 1978 gas fireplace I have in my house. The round metal pipe extends from the top of the fireplace up to the ceiling without touching any walls. Once I remove it all I want to seal off the pipe on the inside and drywall over it. I want to leave the part sticking out of the roof intact in case I decide to install a new fireplace in the future. I have seen a tee cap online which looks like it might work, but I cannot find where to purchase one. I measure the pipe inside my house and it is 22" circumference. Lowe's only has a 6" diameter which is too small. Without busting out the old high school geometery I am guessing I need 7-8" diameter.
Any help is greatly appreciated.

    cap

    divide 22 by 3.14 to get the diameter.

    Thanks, but what I was actually looking for is where to purchase a cap to seal off the old chimney.

    22\" circumference=7\"

    However, if you find any ol' cap/plug and seal the base of the B-vent, you could get condensation in there. Once it fills up a little, you can get ceiling damage or start growing "goobers" in the walls.
