the T on this vinyl bulb seal slides in a slot on the bottom of the window.when shut it the bulb seals the window. The t is an 1/4 inch please advise if you need additional information. I am at the point of installing any alternative that will work.

From your photos, the "T" slot looks a little lighter than 1/4". I believe it is 3/16", which would match our 58-182 weather-seal. What do you think?

No I have tried 3/16th and it falls out of the channel.
do you have something with a 1/4 inch or something that will adhere to an aluminum window subject to weather?

The only other seal that comes to mind is our 58-171. It has a wider leg. This might be the one you are looking for.
