need replacement bubble seal window weatherstripping

Thanks for posting. I believe you have something like our 58-171 or 58-182, but the "T" that actually inserts into the window has broken off. Do you have a sample of this weatherseal with the "T" intact? If so, look at those two suggestions and see if either has a "T" whose size matches yours.

Typically, they just slide out. Are you able to do that, or are the edges of the slot sealed in? If that's the case, then it may be a little trickier. Let me know!

I see. I always hate it when window manufacturers do this. I'm afraid there's not going to be an easy way to solve this problem. The only possible way to get the seal out is to get a razor in the channel to slice it into strips. Then you would just pull the strips out one by one. Getting a new seal is even more of a hassle, since you will have to try to work it in with a putty knife, and even then I can't know for sure if it will work. Not to mention we still need to know what size "T" you have.

Do you think you have room to cut the sealed part of the channel? Would that interfere with the operation of the window at all? I don't want you to cause permanent damage, but in some cases this can work. Look it over and see what you think. Is there also any way I can see a few pictures on where the bubble is on the sash? Maybe if we can see where it installs we can have a better idea of what you can do.
