You can pick that up at any rubber specialty shop which will fabricate you one for about 20 bucks.
I'd be extremely worried about getting a tight seal doing that.
I've done a ton of research on conicals, and I'll probably just go the Blichmann or Morebeer conicals route. More expensive, but I know I won't have any problems. This is at lest another 6 months away--but a conical fermenter is on the horizon.
