Cable seal insert

A method of environmentally protecting an elongate substrate with a cover and a sealing means comprising a sealing material having an elongation of at least 100% and a compression set at 70.degree. C. of less than 30%, which comprises positioning the sealing means around a portion of the substrate and surrounding the substrate with the cover such that the sealing material provides a seal between the cover and the substrate.

Closure assembly

A heat-recoverable sleeve having a meltable or softenable insert inside it, a thermal barrier being located between the sleeve and the insert. The barrier may be crosslinked thermoplastic netting, and the sleeve may be transparent.

Heat recoverable article

An assembly for protecting and insulating a junction such as a splice between cables. The assembly may be repaired or modified without a complete renewal of the junction. The assembly includes a relatively rigid longitudinally split tube which is positioned about the junction. Relatively rigid support means, such as rings, are positioned at the ends of the tube and a plurality of relatively flexible prongs project longitudinally, at spaced intervals, around the circumference of at least one end of the tube. The prongs may be attached to, or formed integrally with the support means. A heat-shrinkable sleeve of length greater than the length of the tube, with the support means and prongs, is disposed about the tube, support means and prongs. At least part of the inner wall of the heat-shrinkable sleeve is provided with a sealant so that on shrinking, the end regions of the sleeve overlying the free ends of the prongs are shrunk down over the conduits and are sealed thereto.
