Question About Gluing Plastics for Underwater

[rob.mwpropane]

I own a drysuit with this exhaust valve installed. The outer black ring has fallen off (it's purely cosmetic). I'd like to attach it back on so it stays put. My go to would be super glue gel to reattach. Any suggestions?

I used a dremmel and got all the old glue off and am ready to go, I just want to do it once and be done (as in maybe super glue isn't the best?).

Thanks...

I would use epoxy... but I'm not a fan of super glue in general (too brittle)
Respectfully,

Or this: Single-Use Epoxy Packets

I strongly recommend the purple packet (Urethane).

Thanks all!

A two-part epoxy designed for plastics like g-flex or most "plastic bond" epoxies the hardware stores carry. Surface prep is everything.
