FIELD: automation engineering.
SUBSTANCE: two-door transitional system contains two flanges, made with the possibility of rigid connection between them, and two doors, usually closing openings, limited respectively by the first and second flanges. The device for checking the tightness of said two-door transitional system comprises a housing (36) having a cavity (38) with an opening (44), means for mechanical connection of the device with flanges, and an inflatable gasket (48). In this case, the inflated gasket (48) is made with the possibility of entering into contact with one of the flanges in the inflated state to enable the tightness test between the first flange and the first door or between the second flange and the second door.
EFFECT: increased accuracy of leak testing.
