Gas tight and water tight cable transits comprise a pair of elements of a rigid material each having a narrow layer of resilient sealing material molded integrally therewith which upon clamping of the elements together in a frame expands radially for sealing against the cable and abutting elements and frame parts. In another embodiment, the narrow portion of resilient material is secured to one end of a cable transit element a pair of elements being assembled end-to-end and clamped together to define a seal intermediate the elements. |
