Replacement of Bubble Seal in Casement Window
A quick learner from Seattle, WA says:

I attach photos of the cross sections of old and recently bought seals. They are very similar dimensionally. My problem is that the new replacement seal does not fit in the kerf easily. The old seal fits well and this may be a consequence of its age. I tried using a normal screen roller without success. First then assuming the new seal is OK, is there a trick or tool in your toolbox that would help installation? Second if you think there is a better solution for this situation [would like to use the kerf regardless] please advise. Width of old seal bulb is 3/8" squished,base on which the bulb is attached is 3/16" and the depth of kerf insert is 1/4". For sure the fins on the kerf insert are very pliable on the old seal but thicker and stiff on the new seal.

It's possible that there is a little dirt or some kind of obstruction in the kerf groove. Try running a small flathead screwdriver into the groove, that might clear things up. Also, wet a rag with some oil and wipe that on the installation leg.
A few years ago replaced the foam weather stripping in my wood casement windows at home. I use the 58-055 and just pushed it into the groove with my hand. It is working very well.
