Sounds like what you're after is an AN900-14 gasket, (or an MS35769-18,
same thing). 7/8 inch ID, 1/8 inch ring width, but 3/32 inch thick. NOT
0.625!
Available from many sources, Aircraft Spruce and Specialty is one:

If they don't know of a source I bet someone will offer to make you a few.
Did you try MSC?
