Yup. Like I said in the first post- I have some freshly annealed copper washers. I don’t trust the manufacturer to soften them up and they are probably somewhat work hardened from being punched out of a sheet of copper. I was hoping someone would know something about dot3 dowty or stat-o-seal washers.

I am also surprised nobody makes a tool to touch up the sealing surface. I wish I had a lathe and a heat treating kiln I’d just whip some up out of tool steel. I could probably make a cutter with my caveman tools but it’d be too much work when I can just get another reman caliper.

Here’s a pic of my annealed washers and the style of captured o-ring I’m talking about. I got a little clamshell kit of them- apparently they’re oil resistant but an overnight soak in dot3 softened up the rubber so I won’t be using these on brakes.
