We have a medium hard (say 90A) seal that is pressed into a block on the OD. So OD is static and ID is dynamic.
We are having issues with leakage around the ID, likely due to the circularity of ID edge.
I can't figure out a good way to measure this circularity. I think Go/No go gages would deform the seal enough to throw off measurements. We don't have a CMM and it would be a challenge to fixture the assembly in a way to use a dial indicator reliable, especially if we need to measure every part.
Any ideas?
