I have casement windows that were installed in 1970. The windows are in good shape and just needs replacement weather stripping. I have posted a pic of the weather stripping profile. It is very hard plastic and I am guessing it's because of the age.Was hard to remove. Can't find anything matching at any of the stores ie home depot.

Take a look at our Bubble Seal section. What's the diameter of the bubble portion of your seal?

I'm thinking the 58-055 bubble seal with angled base looks like a close match, but I can't quite tell if that's how your seal was designed, or if that is just a deformity.

The bubble part is compressed from age, it's elasticity is pretty much gone, it's probable more shaped like a tear drop. Bottom portion is what goes into the 1/8 to 1/4 inch groove in the wood window and is shaped like a "V".

I think our 58-055 is the closet replacement to your original weatherstripping.
