    I have a cressi edy 2 dive computer and the o ring seems to have got a bit crushed in one area.
    They don't seem to sell these anymore.
    Is there a way to make a custom o ring somehow? It's not perfectly round unfortunately.

    I'll check those thanks. Let's say I wanted to go the diy route. Anyway to create a small bead of silicone around our something like that and let it dry?

    I have seen kits where you buy a length of oring material and cut to length then glue the ends together so I know it exists but if there is a proper oring available just use that, alternatively you may be able to simply buy the correct size oring from a specialist.

    Normally I'd suggest this, but the correct o-ring isn't round.

    I doubt that would work.

    I also doubt that Cressi manufacture their own O rings. Take the old O ring, measure it (with a vernier caliper but don't squeeze or stretch it) and compare the internal diameter and thickness with those available at http://www.bearingshopuk.co.uk/orings-seals-clips/o-rings/

    Just seen about it not being completely round. Does the groove it sits in have a shoulder on both sides? If so, a round one will bend to fit. If not, then maybe they do have custom seals made.

    Buy it! doesn´t deserve doing by your own, in the case of that o-ring. If it´s a normal oring like leonardo or giotto you can go to a plumber or an hydraulic service store and buy one cheaper and perfectly fitted(they size the oring).

    The battery you can buy it as a package or you can find easilly in a hardware store is a common model. It cost me 4,5 pounds 2 batteries.
