gaskets for port holes

[Whiffle English]

I am restoring a couple of old bronze port holes for use in the cruiser I am building. I believe the ports came from an old Mathews, but am not sure. I am looking for a source of gaskets for them. The gaskets themselves are square cut and 6" in diameter. Anyone got ideas as to where I can find gaskets for these?

McMaster Carr (http://www.mcmaster.com/) Has various shapes of o-ring stock including square. Cut the length you need and glue the ends together, might be able to use with the ends just butted not glued.

If the joint is at the top, it won't be exposed to pooled water and will be less likely to leak.
