Abstract
A seal that enables an enclosure to be sealed and to keep an air pressure balance between an internal space within the enclosure and an external space outside the enclosure in such a way that water ingress into the enclosure is hindered in a predictable manner. This is accomplished by providing a seal having at least one small diameter tube with at least an inner surface being hydrophobic, oleophobic or omniphobic. The seal is mounted in the enclosure between the inner and outer space. To further avoid small particle contaminants to enter and go through the at least one small diameter tube, it is preferable to have a small diameter tube with curves and bends, and it will still allow an airflow through it if there is an air pressure imbalance.
