Port hole Flange Gasket

[Mike]

always one issue leads to another.  I am replacing the rubber gaskets on perko port holes of a CP19.  Upon receiving the material from Hutchins, it is different from the original item.  The new material is "T" shaped while the original rubber was a a "U" channel which fit into to the regress of the port. 

Question 1:   How does the new material fit into the port?  The cross of the "T" is wider and thinner than the base.

Question 2:  What is the preferred adhesive to use in attaching the gasket to the port when fitting?

Mike:
   I was lucky to find some old Perko gaskets at Fawcett in Annapolis before they folded. They may have reopened, don't know. It was a fun job removing all 6 sashes on my 23, removed all the old gasket material, cleaned them while they were off. I think I just used silicone to hold the gasket in place, reinstalled it and locked it closed but now too tightly until the silicone cured. 5 of them were perfect- never leaked. One extremely recalcitrant one continues to drip a little. No big problem.
   It sounds like they may have sent the wrong gasket. Can you post a photo here?
