A hermetic seal has the quality of being airtight. In common usage, the term often implies being impervious to air or gas. When used technically, it is stated in conjunction with a specific test method and conditions of usage.
Famous quotes containing the word seal:
“Eyes, look your last.
Arms, take your last embrace, and lips, O you
The doors of breath, seal with a righteous kiss
A dateless bargain to engrossing death.”
—William Shakespeare (1564–1616)
