Abstract: A device for sealing of conduits inserted in circular lead-throughs of walls and roofs designed as a frame is provided for the arrangement of a plug formed sealing body of elastic material which forms a quadrangular pack accommodation. In the pack accommodation elastic splitted modules in square form are inserted with received conduits and arranged sealingly by clamping elements acting on the sealing body. To increase the pack accommodation for an assembly and disassembly of the modules it is so provided, that at least one boundary side of the pack accommodation forms a free space for receiving an insertable part element after assembly of the modules. The part element forms a part of the sealing body and is designed as horizontal segment of a part of the depth of the sealing body.

Abstract: A sealed feedthrough or bulkhead for cables or pipes in a wall assembled from modules having block-shaped members defining spaces in which a test pressure can be applied, utilizes spacers between the block-shaped members which maintain gaps between them while having pins extending into the block-shaped members.

Abstract: Modular rectangular parallela pipidle sealing units assembled in a frame for a gas tight penetration seal have perimetral grooves and bores reaching from these grooves into the recesses of the modules to the peripheries of the cables or pipes or filler bodies in the modules. The grooves and bores form a pressurizable network which after pressurization with compressed air can be monitored for gas tightness.
