Tyco Heat Shrink Cable Entry Seals

Heat Shrink Cable Entry Seals

Heat-shrinkable cable entry seals (CES) provide a watertight, fume-tight seal where cables enter connection boxes, bulkheads, or other enclosures. CESs are available in two basic types: standard and threaded.

The standard CES for thin-wall enclosures consists of a three-part assembly – a rigid nylon nut, an O-ring, and a heat-shrinkable molded body. The CES for threaded-hole applications is a one-part assembly that combines a tapered national pipe thread (NPT) in rigid nylon with a heat-shrinkable molded body. To meet sealing requirements, all CESs have factory-applied adhesive that provides the seal to wire and cable jackets.
