ABSTRACT:
An apparatus and method to pressure seal cable splices utilizing a forced encapsulant, the apparatus comprising a sleeve having an interior and exterior surface, a first end, a second end and a longitudinal slit having a longitudinal edge along each side thereof. The slit can be widened and thereby alter the diameter of the sleeve. A pair of locking flanges are 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. An inner flange is 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. An end cap is located at each of the sleeve ends and each has at least one opening therein to permit the passage of a cable therethrough. The apparatus includes camming brackets to secure the locking flanges adjacent one another. Additionally, the apparatus may include an end cap pressure indicator dome which indicates the splice has been properly sealed by the encapsulant which is inserted into the sleeve prior to closing the sleeve.
