Need help with locating window sash seal for Anderson double hung window

Thanks for posting! We do not have a direct replacement match for the Andersen bubble seal you have here. That said, I do believe our 58-053 Kerf Mount Bubble Seal could potentially work for your repairs.

Your bulb appears to be a bit smaller in diameter, so I cannot guarantee that it will be a fit but take a look and see what you think!
