Original Note:
The zipper enclosures on Armstrong’s spacesuit actually consist of three layers. Two brass zippers sandwich a rubber layer: zipper, rubber, zipper. When pressurized from the inside of the spacesuit, the rubber expands and creates a seal between the two zippers. https://airandspace.si.edu/stories/editorial/shepard-armstrong-spacesuits-8-fun-facts
