Replacement gasket for G-U doors

A home owner from Los Altos Hills, CA says:

We have G-U sliding doors and the seals where the vertical part of the door meets the jamb are failing - they are very sticky and pull out of the kerf they sit in when the door is opened.

I've looked around and can't find anything equivalent. I've tried a different kind of kerfed gasket but it was too thick and prevented the door from closing all the way.

Do you have anything that would work in this application?

The gasket has a Y cross-section, with the kerf insert the base of the Y and a piece of rubber extending in the other two branches of the Y. Most gaskets I can find extend only in one direction and fold back on themselves, which make them hard to squash enough to get the door closed.

I'm afraid that I couldn't find anything like this. Can you tell me the dimensions of the end profile of this glazing?

A home owner from Los Altos Hills, CA says:
The kerf insert is ~3/8" deep. The outward facing portion is not quite 1/2" wide.
Maybe 5/16" on the wider branch and 3/16" on the thinner branch.

I'm afraid that I could not locate an exact match for the weather seal in you patio door. Do you think you could use the 58-056E as a substitute? If not, I recommend contacting the supplier of the door or the manufacturer to see if they can supply. And one last thought, you say it gets sticky from the heat. Try using a silicone spray on it to see if that helps.

A home owner from Los Altos Hills, CA says:
That 58-056E looks like the one I already tried, it's too thick. When installed the door can't close enough to latch it. I guess I could perform surgery on it to hack off half or more of the foam part.

Thank you for all the help!

Even though you said your seal is for a door, it looks very small. I'm wondering if you could use something like our 58-053, which is designed for windows. 

You can order a sample of the 58-053 from this page. That will let you try it out and know for sure.
