Help: O-Ring from Subal viewfinder

Dear all,

I am flying in 3 hours to the Red Sea.

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.
