What is the exact inside diameter of the 3/4" size?

For both 3/4 PVC Schedule 40 and 80 pressure fittings the socket diameter would be: Entrance: 1.058 and Bottom: 1.046 with a tolerance of +/-0.004. There is a diagram available at https://www.charlottepipe.com/Documents/DimensionalCatalogs/Pressure_Pipe_Fittings.pdf for additional information. Thank you for reaching out to Charlotte Pipe!

how tall is the 3/4”

as the circunfrenciment at least 1/4 x 2 1 1/4 inch or Hight from top to bottom standing up would be about 1.5 to 2 inch

What is the exact inside diameter of the 1" size?

I measure 1.3" ID. It's too big for my 1" pvc pipe.

Does the pipe section need to be completely flush with the coupling center stop/divider in order to have a proper seal?

yes as close as you can get it if not in far enought it might come apart or leak . you might have to cut it out and start again if not in right .
