I'm looking for Bubble Seals for my Vinyl Windows. Windows are Diamond Line 2000 from the Lumber Yard installed in 1999. Seals are dry rotted and I am looking to replace them.

See the 58-055 Offset Bubble Seal. Compare with your old hardware and see if you think this could work for you.

Bob,
The bulb dimensions look "OK" but the orientation of the barb needs to be in the opposite direction.

I was able to take the sash out and was able to access a piece of seal that was deterred the whole way. New dimensions and photo attached.

Thanks for posting. This actually isn't a kerf at all, but a T-base. With that in mind, see the 58-171, 58-182, or 58-183. Compare with your old seal, double-check the dimensions, and see if one of these might work for you.
