I agree.

Too much squish is actually worse then not enough. Only 0.002" (0.05 mm) squish is actually adequate for our application. I opted for 0.012" squish because that is what an engineer at my work recommended as a maximum. I wanted the block to seal even under a lot of pressure even if it will never see it. To keep it from leaking under near zero pressure, all you need is for the rubber to be touching both surfaces, but of course a little squish is better for peace of mind.

If you over-stress the rubber, it is more likely to fail.
