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.

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I understand that SUUNTO has just withdrawn their Wireless transmitter battery kits.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 !
