weatherstripping for casement windows

A home owner from Chicago says:
Windows are 25 years old and have the original weatherstripping. 1/2" overall length, 14/" bulb & 1/4" stem. What do you have that will fit .

Thanks Peter

Hi, Peter. Have a look at our 58-053 bubble seal, which seems to match yours. How well could this work as a substitute?
A home owner from IL says:
I need a bronze bubble seal, for the bottom of pella door sill. 1/2 inch bubble, with the similar to the 58-114 push in locking mechanism . 3/8 inch bubble too small.

Unfortunately, we don't have a version of the 58-114 that's as large as 1/2". The 3/8" version we sell is the largest we're able to provide at this time.

I'm very sorry for the inconvenience.
