While packing now my gear I have removed the Subal straight viewfinder. One of the 2 O - rings came out in 2 peaces.
Can anyone tell me if I can still use it with one o-ring only????
Thanks for your help.
Cheers

Yes you can use just one o-ring but I would not recommend it. The second o-ring is a backup seal but it also helps stabilize the viewfinder from sideways movement.
Since you don't have a spare you should try to locate one. Any well stocked scuba store might have one that will fit. You can also try a hardware store in the plumbing area. I realize you do not have a lot of time to get this.
The o-ring is a metric o-ring 32mmx1.78mm that converts to a american 2-026 o-ring. That o-ring is used on a princenton tech 40 light http://www.princetontec.com/tec-40 .
I hope that helps.
Dear blibecap,
Thanks for your answer. I am right now on the plane starting I the next few minutes without a 2 o-ring.
Hope that someone on the boat can help me out.
I will check tonight when I'm on the boat.

Just if anybody else needs this information:
I have been diving now one week in the Red Sea with one o-ring on the subal 180 viewfinder without any problem. Contacting Subal they informed me that one O-ring is not recommended but sufficient.
