Sliding patio door bottom weather seal

Help! Looking to replace the bottom weather seal under the sliding portion of my patio door. It is cracked and splitting. It is 36 1/2" long. Looks like an extruded, foam-filled vinyl bulb with tiny ribs. It fits into a slot on the threshold. House was built in 2005. Absolutely no manufacturer ID or label of any kind. The close-up end view shows the (squashed) profile of the seal, which looks like it is foam filled. If you can identify, I'd love to buy some from you. Thanks!

Hey there,
Thanks for your post! I believe you may be able to replace your sliding glass door seal with either the 58-173 Push-in Vinyl Bulb Weatherstrip or the 58-181 Pella Push-in Bulb Weatherseal. Carefully look over each of their dimensions to determine if either could be a fit.
If neither of these is a match, I'll need to see a clearer photo of the the end profile of an undamaged piece.
