Method and apparatus to pressure seal cable splices

An apparatus for sealing cable splices comprising:

• (a) a sleeve having an interior and exterior surface, a first end, a second end and a longitudinal slit having a longitudinal edge along both sides thereof and which is able to be separated and thereby alter the diameter of the sleeve;
• (b) a pair of locking flanges secured to the exterior surface which extend longitudinally adjacent each side of the longitudinal edge and which may be cammed together to close the longitudinal slit;
• (c) an inner flange located along one longitudinal edge of the longitudinal slit which extends peripherally and is adjacent the inner surface of the sleeve when the pair of locking flanges are releasably secured together;
• (d) an end cap located at each of the first and second ends of the sleeve, the end cap having at least one opening therein to permit the passage of a cable therethrough;
• (e) means for releasably camming the locking flanges adjacent one another;
• and
• (f) means for indicating the internal pressure in the sleeve when an encapsulant is inserted therein, the means for indicating internal pressure being located on at least one of the end caps, the means for indicating the internal pressure in the sleeve comprising a dome which is generally concave to the exterior surface of the end cap when the pressure in the interior of the sleeve is at a first internal pressure and is generally convex to the exterior to the surface of the end cap when the pressure in the interior of the sleeve is at a second internal pressure.
