Weatehr Stripping - Windows

Hi,

I would like to get the correct part to replace weather stripping on my casement windows. I think the manufacturer is HUNT.

Attached is a pic. The L section is 1/4 of an inch on either side, with one small groove/spike to hold it to the window. The bubble is also around a 1/4 inch diameter.

Please let me know my options. Would like a better quality seal if possible. The windows are in a 15 year old house.
