watertight seal
Moisture-blocking barrier junction
A watertight seal is a closure that prevents water from passing through.
The term applies to physical barriers—gaskets, O-rings, caulking around bathtubs—that keep water in or out: Check the watertight seal on the hatch before we dive.
Figuratively, a watertight seal suggests absolute security or containment: The investigation maintained a watertight seal on information leaks.
