Help replacing spider gasket - glue or no glue?

I have a very old Davey multiport valve which needs a new spider gasket. I have the new gasket ready to go in and from a previous inspection of the faulty gasket it was lightly glued in with a black silicone sealant of some sort. I know some gaskets need to be glued in and some don't depending on the brand of valve, but mine is so old I don't know whether I should glue it or not.

Should I just glue it in or install it without glue to start off with to see how it goes?

Cheers!
