On this bubble seal, bubble is 1/4 " height and the base that slides in the grove is 3/16"

I'm afraid we don't have a bubble seal in that size. Can you confirm the size of the bubble itself? It seems to be compressed, so make sure to compensate for that in your measurement. In the meantime, look at our 58-053 and see if you could use this.
