My problem is that a 3/4" ID is too small and a 7/8" ID is too big. I can't find a 13/16" ID SS washer on Mcmaster. Maybe I could file or drill out a 3/4" washer?

Drilling a 3/4" ID washer out is pretty tough. Holding it securely while you drill it is a problem.

Teflon tape on the threads should seal it fine to the locknut if you choose to solder or braze the nut to the keg.

I can get a 3/4" washer to thread on half way and then it gets to tight to move by hand so I'm thinking I can either turn it with pliers and it get it all way on or use a file and just open it up a touch

Don't try to force it to thread as you will eat up the male threads and jam it on after a couple turns.

If you have a vise you can grip the edge of the washer and use a file on it to open it up enough like you said. A drill with a grinding stone or burr bit would work too but it will eat up the stone fairly quick.

Assuming you have a step bit that you drilled the 7/8ths holes in the keg with, you can chamfer the washer hole on both sides until it threads all the way down the fitting without force.

What size washer do you supply with your weldless sightglass kit?

All of the weldless kits come with a metric M20 ss washer.
