Beschreibung
Zusammenfassung:	The present invention relates to a sealing system with an O-ring arranged in a compressed-air pressurized groove that provides for explosion proof sealing in explosion proof devices or devices resistant to explosion related pressure surges. In the sealing system in the explosion proof devices of the invention, an O-ring (3) is arranged in a rectangular groove of a top flange (1 ) and abuts upon a bottom flange (2), wherein the pressure of the O-ring (3) against the bottom flange (2) is provided for by a supply of compressed air pressure through a connection (4), when the pressure in a container abruptly increases, the pressure presses the O-ring (3) towards the external edge of the groove and penetrates past the internal edge above the O-ring (3), thus yet additionally pressing the O- ring (3) against the external edge and additionally sealing the joint.
