window seal

I have a sunporch that has 7 North American windows (various sizes). The window seals are in varying stages of decaying. On a couple of windows, the round foam part has come completely off. The seals are on the bottom of the window. Hopefully you are able to see the 3 photos I uploaded. Are you able to identify the parts? If so, do you carry the parts I would need?

thanks for any info!

I have uploaded some more photos that will hopefully help you determine if you might have the parts I need. The bubble is attached directly to a the t-piece you can see in one of the pictures. If I tried to remove it from the sash, the t-piece would have started breaking up into pieces. Without a replacement part, I can't do that.

I have 7 windows and the bubble has fallen off 5 of the windows as it rotted away. 3 of the windows are 30" wide, 3 are 28 1/4" wide, and one is 15" wide.

let me know if I need to try to take different pictures. I am hoping that you are able to help me find replacement parts!

thanks,
Betsy
