"Filling The Gaps"

No, sink tubes are labeled by their ID. That's why 1.5 inch sink tube fits over Tim's parts, which have an OD of 1.5. What you need to do is figure out the wall thickness (ie gauge) of your 1.25 inch pipe and then add that to the ID to figure out the OD. Or you could just measure it. Or you could save yourself the hassle altogether by realizing that online metals won't sell a tube that will fit exactly over a 1.25 pipe and under a 1.5 pipe. Get the nearest thing, which would be a tube with a 1.25 ID, and then you'll have to sand down the inside of that tube to get it to fit over the sinkpipe. It wont be easy, but it's been done before.

And Rhyen, what are you talking about?

Also, just for the record, don't use a tape measure to measure pipes or tubes. Use calipers.
