help needed to identify bubble seal

This sill track exterior gasket has a hard plastic base 5/16" wide. Originally the back of the base had adhesive which held it to the sill track. The plastic base was vertical against the track and one edge of the base fit into the tiny track next to the sill track. The diameter of the tube is 5/16" as well. As you can see, there virtually is no riser plastic between the base and the tube. The tube itself is very flexible, rubber like. This piece lasted about ten years. Sliding door manufacturer is unknown. I hope you stock it. Thanks for this service.

Thanks for posting.

I recommend starting with the 58-134. Keep in mind, the design is different but the dimensions aren't far off from the 5/16" measurement you are in searching; 9/32" x 9/32" is only 1/32" off from the given size. Take a look and see what you think.

Jasmine, thank you for your suggestion. The issue with it is the riser. We tried other options but, like this one, the backing, riser and tube looks too "tall." That creates friction between the track and the door's tunnel so the door won't slide or won't slide easily. There needs to be a tight fit between the tube and the hard back piece as shown in the photo. The one I need may be proprietary to the manufacturer.
Other thoughts?

Thanks for explaining, that makes a lot of sense. I regret to say that the only other "T" slot bubble seal we sell is the 58-135 but its dimensions are way too different from the specifications you would need; the closest match in our inventory being the 58-134.

I do sincerely apologize that we are not able to provide a better replacement recommendation.
