Weather Seal for Unknown Brand of Window

A quick learner from Texas says:
May 25, 2020
Would you be able to identify this weather seal or an appropriate replacement? The opening of the channel on the bottom of the sash is 1/8".

General info: This is a non-tilt, single hung window with no brand markings. I cannot find a way to remove the lower sash. There are no clips in the side channels or attachments at the bottom of the sash. So it does not appear I would be able to "slide in" replacement seal because the sash cannot be removed. Can replacement seal be pushed into place from below and is there a specific technique or tool for this that does not tear the seal?

Thanks!

1/8" is very narrow for bubble seal on the bottom of the sash. It is usually 3/16". Look at our 58-135 and see what you think. In regards to installing the seal in a groove on a non take out window, you would slip one side of the "T" leg under the lip and work the other side with a putty knife to slip it under the lip.
