MCT Brattberg supplies a pressure-resistant, round transit that is suitable for the watertight penetration of a pipe or cable from 4 to 100 mm: the SR Seal. The SR Seal consists of a galvanized steel or stainless steel sleeve and a round element for filling. The steel sleeve is intended to be welded into a steel wall or deck in a suitable round hole.
The filling element is made of silicone rubber and finished with stainless steel 316L mounting parts. The rubber of the SR Seal consists of a core and 1 or more round rings, which can be removed to be able to seal the cable(s) appropriately. If the core is not removed, the SR Seal can also be used as a blind transit, for example to feed a cable or pipe in the future.
The SR Seal is available in eight sizes. After the SR Seal has been made suitable for the cable to be fed through, by removing the core and possibly 1 or more rubber rings around the core, the cable can easily be fixed by tightening the Allen screws, which are located on the round filler element.
To feed through existing cables, the rubber parts of SR Seal can be supplied cut or opened on site using a utility knife.
