Hi, I need to replace a leaky gasket on a Pella casement window. The number is PELLA-STC-0405-PLCCMLH1Z2-025A059ABRN-521S-NFRC. The gasket I want to replace inserts into the fixed part of the window frame, not the opening casement.
Thanks, Henry

Hi Henry,
Thanks for posting! I'm afraid I cannot recommend a replacement for your Pella seal based on the brand and window information provided. I'll need to see a photo of your existing seal, from an end profile view to determine if there's a recommendation we can make.
Take a look at the video tutorial below for reference.
