Heat-shrinkable feedthroughs for reliable sealing protection
Feedthroughs provide environmental sealing and screen continuity to a bulkhead as a cable passes through. In our feedthroughs, the assembly consists of a specifically designed locknut and O-ring seal, onto the rear of which is preinstalled a Raychem heat-shrinkable molded part. Installing our feedthroughs is simple and easy: Simply tighten the locknut on the rear of the bulkhead. This compresses the O-ring; a small knife-edge establishes electrical contact between the assembly and the bulkhead.

By applying hot air to a molded part, this forms a seal to the cable. For screened cables, the assembly includes Raychem molded part and a conductive adhesive for electrical continuity between the screen and the bulkhead. These molded parts are manufactured as shielded (screened), heat-shrinkable parts designed for shielding levels 80 dB at 100 MHz.
