ABSTRACT:
A splice between two multiconductor cables is protected from ingress of water by a closure which is filled with a sealant which is pressurized by a bladder inside the closure to a pressure sufficient to force the sealant into the interstices of the splice and the interstices between the conductors in the cable, and the pressure is maintained by the bladder until the sealant cures or hardens.
