Pete:

Your best bet would be to get a set of dental picks so that you can take
the old O-ring out, and then just put a new O-ring, or one size larger
O-ring in for a better seal.

Here, I wrote up a blurb about O-rings while I was posting on a board
before I came here. Lemme find that write-up.
The "o-ring" on an underwater camera case is not a round o-ring you
can readilly get a replacement for - it is generally a pretty long
o-ring formed to fit the perimeter of the case.. And no dental pick
required to remove it.
