The best glue for silicone disks is cyanoacrylate adhesive e.g. Krazy glue,. If you can additionally suture the disk, it will be the best solution. The procedure is described here: Full-thickness splinted skin wound healing models in db/db and heterozygous mice: implications for wound healing impairment. Park SA et al.

Crazy glue is the clear glue that dry up very fast (Cyanoacrylate) you need to apply very little on the silicone disk (aka = o-ring) and hold the ring down for 30 to 60 seconds so the skin will attache to the ring. I recommend to use 6 or 8 interrupted cruciate suture knots for holding the o ring in place for the 2 weeks.
