Abstract
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.
Claims9
A gas tight and water tight cable transit comprising:
- first and second elements each having first and second body portions of a rigid material and a layer of resilient sealing material interposed between said first and second body portions of said elements and formed integrally with at least one of said body portions, and said elements being adapted to be assembled together with opposing surfaces defining a cable receiving through bore extending transversely to the plane of said layer of sealing material, and means clamping said first and second elements together thereby compressing said sealing material between said rigid body portions, causing a portion of said sealing material to expand radially inwardly into the through bore to provide a seal between an inner surface of the bore and an outer surface of a cable extending through the bore defined by said elements.
A gas and water tight cable transit comprising:
- an elongated tubular member having first and second portions of a rigid material, a layer of resilient sealing material between said first and second portions and permanently secured to at least one of said portions of said member, said layer of sealing material extending transversely to the longitudinal axis of said member, and said member having a through bore extending axially thereof through said first and second portions.
A gas tight and water tight cable transit comprising:
- first and second elements each having first and second body portions of a rigid material and a layer of resilient sealing material interposed between said first and second body portions and formed integrally therewith;
- said first and second elements having respective first and second surfaces with a generally semi-circular channel therein which extends axially of said element, said elements being adapted to be assembled together with said first and second surfaces opposing one another and the channels therein aligned one with the other to define a cable receiving through bore extending transversely to the plane of said layer of sealing material, and means clamping said first and second elements together thereby compressing said sealing material between the body portions thereof causing a portion of said sealing material to expand radially inwardly into the through bore to provide a seal between an inner surface of the bore and an outer surface of a cable extending through the bore defined by said elements.
