I have a connection that has a custom-shaped hard plastic gasket with strong adhesive to hold the two sides together. The gasket is meant to fill the gap between the two pieces and the adhesive bonds them together.
I have to do repair on this connection which requires that the gasket be completely removed from both ends which damages it in the process and it cannot be reused.
Is there some form of soft silicone or other kind of adhesive that I can use to fill this void that is strong enough to bind the two ends but not permanently in case I need to remove it again? I can't use a normal glue because it flows too easily and I don't want to use epoxy because I'm afraid that I won't be able to separate the parts again.
