I didn't look for your specific gasket but this company had a nice range: http://www.gvc.net/ - got some Euro bevel gaskets through them.
I'm looking for these gaskets and I'm not having much luck. Dixon-Bradbury was backordered and what they have on BO is less than what I'm looking for.
Anyone have a stash or know of a supplier I haven't thought of...
I order my SMS gaskets from Newlands.
Call Gould Stainless Steel or brewerygasket.com
Archon Industries is good for them.
Palau Brewing Company
Just for future reference we now have these gaskets available 1" to 4" sizes in EPDM.
We stock these gaskets as well.
