AND FOR THE TARDS WHO THINK SPACE IS JUST GOING UNDERWATER IN REVERSE....

You're not getting it.

The pressure isn't the problem. The vacuum is. Hard vacuum (10^-6 torr or greater) causes materials to outgas. This means the material weight is literally reduced by the vacuum as molecules of it turn gaseous and float away. The seals are elastomers, which are especially susceptible to outgassing.

There's a whole field of materials science related to using this to create thin coatings.

The hard vacuum of space is a uniquely hostile environment to man-made materials.
