NEC are a range of polyolefin semi-rigid heat shrinkable end caps, which are coated internally with a hot melt adhesive. They offer a quick and very effective method of sealing against moisture in most types of communication and electrical cables. NEC are also resistant to corrosion, abrasion and mechanical damage.
