Helium can leak through welds that are impervious to other gases (and all liquids) because it is such a small atom. Helium is often used to test the integrity of welds in tanks. The detectors literally measure the leakage in the number of atoms passing through unimaginably small voids in the welds. Usually not a big deal.
