Replace weather stripping on 2001 Owens Corning replacement windows

Question

Trying to find the right weather stripping to replace/refresh my Owens Corning windows. House built in 1949, windows replaced in 2001. Windows are still in good shape but some of the stripping (the stuff outside facing) is brittle and starting to fall off in the middle. The foam part seems OK but clearly this all needs to be replaced. Might as well replace the pile weather stripping at the same time. 21 windows

Thanks for posting. For the foam seal, it depends on how that T-Slot attaches. If it's offset, as seen in the diagram below, something like our 58-183 might be best. If it was just directly beneath the bubble though, our 58-135 might do the trick (the fact its a hollow bulb, rather than foam, shouldn't make a difference so long as the dimensions match). Compare the diagrams below to your old bubble seal, and let me know if either of these seem to match, or if anything differs, and if so, by how much.

For the wool pile, you'll need to measure the exact size of the base, and then the height of the pile. Wool pile dimensions are very precise, often going into the X/32" range, so be as precise as you can. If you can tell me as best as you can those measurements, I'll do my best to find matches from our selection here.
