Replacement gasket

I need to replace the rubber weatherstrip on our Pella double glass doors. I believe that it is the 3/8 inch gasket that you sell but want to be sure before ordering. The doors are wide, tall double pane sliding glass doors installed in 1992. Thanks

I'm so glad I found experts who can help with tricky questions. My house is 120 years old. The weather stripping in the back door has been there for at least 40 years. My fear was that it was too old to find proper replacement and would require serious work. Bulb rubber strip inserts into a metal strip that frames the door. See images. Smaller than most I see online. Any/all suggestions would be much appreciated. Thank you!
