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.
