Where 2 buy 3+ inch stainless 0-rings?

Marine shop? Kite store? Camping or climbing gear? The best I could find at West Marine was a 2 incher.

Is this for kiting? Pretty heavy.

To answer your question: http://www.mcmaster.com, "316 SS welded ring".

If you are in the States or Canada, I've had good luck (and lower prices) with

and use the search term 'o-rings'

Looks like they carry sizes to 3 1/4"
