Portlight Gasket replacement

[Rex Delay]

My ancient portlights need new gaskets. I have bought neoprene cord to make new gaskets from but curious as to best method to adhere them to the plastic frames. Friction alone, instant glue or Sikaflex. Other options. Old discontinued PYHI ports.

3M Glazing tape, industrial grade.


Avoid neoprene solutions. UV gets it sooner.

Used 1/4" neoprene cord from McMaster Carr. Used Gorilla instant glue. Gasket fits in a channel in the interior, very little UV. Now with new, soft gasket, do not have to tighten the ports as much to prevent leakage. Works perfectly!

the gaskets i bought from mcmasterr had the glazing tape already adhered. almost three years and no adhesion issues yet.

Minimum amounts of super glue.
