    My questions is not limited to computers. I am looking to put together a save-a-dive kit (including O-rings for my computers). I am looking at the cost difference between the Buna-N O-rings and the Vitol O-rings. The price difference is negligible. Is there any danger in using Vitol O-rings versus Buna-N? Applications include battery door (2-023), tank rings, LP hose, etc. I am a Nitrox diver, but have a set of equipment dedicated to that purpose, so it should not have any bearing on this (separate save-a-dive kit, too). Any thoughts would be greatly appreciated.

    There are no disadvantages that I can think of other than price, which as you've pointed out is negligible. An advantage of using Viton or EPDM is the indefinite shelf life.

    Suunto Mosquito o-ring battery:
    Metric Size: 20.0 x 1.3 EPDM 70

    Could anybody edit the "Computer Batt O-ring" document ?
    Thanks in advance.

    PS: possibly the D3 has the same size

    I understand that SUUNTO has just withdrawn their Wireless transmitter battery kits. Apparently they attribute the cause of the recent product recall of their Transmitters to Users over-tightening the screws when replacing the battery. Personally, I think a metal female thread insert moulded into the housing would have prevented the cracking issue.

    So if you do DIY replace your transmitter battery, please remember its the O-Ring which seals the flange and do not over-tighten !
