Device for feed through of e.g. optical waveguide into portion of e.g. wall, has outer gasket device comprising primary seal and secondary seal that is compressibly extended between primary seal and wall portion

摘要

The device (1) has two closing elements (3) comprising a portion for retaining a tubular element (5). An outer gasket device (10) comprises a primary seal (9) and a secondary seal (11), where hardness of the secondary seal is lower than that of the primary seal. The secondary seal is compressibly extended between the primary seal and a wall portion. The gasket device completely extends outside an aperture to seal the aperture against the wall portion. The closing elements comprise a connection that comprises a closure element for closing an inner cross-section of the connection.
