A plug door is a door designed to seal itself by taking advantage of pressure difference on its two sides and is typically used on aircraft with cabin pressurization. The higher pressure on one side forces the usually wedge-shaped door into its socket to create a seal, which prevents it from being opened until the pressure is equalised on both sides. A non-plug door relies on the strength of the locking mechanism to keep the door shut.

Passenger trains
of the Munich U-Bahn uses sliding plug doors. Many passenger trains in the world use sliding plug doors: early examples of passenger trains using plug doors include the MVG Class A of the Munich U-Bahn from 1967, the first batch of trains for Line 2 of the Milan Metro from 1970, and the DT1 of the Nuremberg U-Bahn, also from 1970. Recent examples of trains with plug doors include the KTX-Eum high-speed train, the Gautrain commuter train, and the E-class tram in Melbourne.
Deep-sea vehicles
Deep-submergence vehicles such as the Alvin use a plug hatch which is sealed inward by the pressure of the ocean water.
