There must be some reason why I would choose this product to block an unused thimble (flue) rather than an end cap?
The plug adapts to a range of sizes, you insert the plug then tighten the center screw which expands the plug and creates a tight draft-proof fit.

I converted my wood-burning fireplace to ventless propane. The damper in the fireplace is broken and the previous owners installed a cap. Can I use this to seal the hole left by the damper to keep heat from rising into the closed chimney?
We do not recommend using this cover in your application because this cover is only meant for use over thimble openings in walls, not inside a firebox.

We are purchasing a home that currently has two woodstoves exhausting into one chimney flue. Our homeowner's insurance says that one needs to be removed and capped before they will insure the property. We are electing to keep the woodstove on the lower level (basement) and remove the one on the main floor. Would this product adequately seal the thimble where the main floor wood stove is removed? Would we still be able to use the lower woodstove with this in place?
This would indeed work for your application. It uses the center screw to expand and make a seal in the thimble.

My hole coming through the wall is an insulated 12” dia pipe and I need to close it off. Do you have anything that will fit this?
We apologize but we do not have a flue cover that large.

On the front of the Insul-plug, what is the screw for? What are the installation instructions?
The screw attaches the actual pan cover to the 'plug" . It fits tight into the pipe, exactly like a drain plug for a bathtub.

Since the plug adapts to a small range of sizes, you insert the plug then tighten the center screw, expanding the plug and creating a snug draft-proof fit.

If I am disconnecting my wood stove, can I use this product to plug the hole in the brick chimney?
This can indeed be used for that purpose.
