About Canon O-Rings

[Randall]

I've seen lots of o-rings in my day....and the one that came with the Canon U/W housing I own (still brand new with only 5 dives) just doesn't seem to be of the best quality compared to o-rings supplied with many instruments used in other industries. So far it's done its job, but I just don't like what I see or feel when I inspect it before sealing my camera up in the housing. It's just not nearly as perfect as I've seen and I can see/feel tiny imperfections (tiny lumps and small pieces of rubber) in various locations around the ring not present in other o-rings.

Has anyone researched other suppliers of industial o-rings? I really feel that there are better o-rings available and I've thought about getting measurements (diameter/length) and trying to find a better quality product....There are many different materials available including silicone rubber out there. Anyone?

My camera with the Canon supplied case and O ring has made 50 or so dives including down to 120'. System seem pretty durable and no problems.

Can't say that I have done any research but my canon a70's o-ring has done it's task. Haven't noticed anything funny about the o-ring but then again I'm not an expert on o-rings. What camera do you have? I've done some 50+ dives with my a70 and had no problems with the o-ring. Althoug now I'm upgrading to oly c-8080 and pt-023. We'll see how things turn out with that set

Almost 200 beach dives on my A70 and no problems yet--knock on wood.

I changed out the main o-ring at about 130. Anyone ever change out the other rings?

Another vote for it doing its job. My A20 has over 400 trips to the ocean on its original orings; my A70 had over 150 and the A75 is coming up on 100.

I have never messed with the other orings - they all seem perfectly ok.
