Abstract

A seal between an object such as a cable, cable splice or branch-off, and a surface such as a recoverable sleeve by means of a flexible envelope containing a void-filling composition. The void-filling composition undergoes a change from a low viscosity on installation, which allows the flexible envelope to conform to the object, to a high viscosity after installation, which gives mechanical strength to the seal. Deformation of the flexible envelope on installation may be brought about by installation of the recoverable sleeve or other surrounding surface.
