Need replacement "leak seal gasket" for Milgard C650 Ultra Casement fiberglass windows installed in 2009.

One picture is the Sales Order Number on one of our windows. The 2nd picture is of a piece of removed leak seal gasket. This type of seal goes on top, side and bottom of these roll out casement windows. The seals have deteriorated and allowed hard rain to leak in. Need to identify the replacement seal for this application.

Thanks

I'm going to send two pic. one is a much better profile of the leaf seal that goes on the edge of my Milgard windows. Pic of seal on edge of window. Seal is only on the top and side of these crank out casement windows.

Emily,,

I had been looking further and realized that your Kerf 58-200 product seems to have the exact same measurements as the sample profile piece I took out of the window this AM.

Thanks for your research and follow-up.

Great help.

Thanks

Jerry
