API requires seal chamber face runout

I don't understand, can you explain it?

The diameter of the sealing cavity is 100mm, and the end face runout is less than 50μm=0.05mm

Do we still need to see what kind of seal it is?

The requirements mentioned above are API requirements. The sealing factory's requirements may be looser or stricter.
