Try looking at electrical cord grips. They are used for industrial wiring of stranded wire cables to a knockout hole in an
electrical box.
Some are made with an O-ring so they seal to the electrical box. The grommet that seals against the "cord" allows for diameters
from 3mm to 11mm usually -- just by hand tightening a molded plastic cap
