That is a brass crush ferrule seal. You put the nut on the white plastic hose; slip the crush seal on next; then fasten everything to the brass fitting.
When you tighten the nut, the crush ferrule seal pinches the white plastic hose making a watertight seal.
The silver tapered tube goes inside the white plastic hose to provide the hard surface for the ferrule to crush against.
