TE Connectivity's cable entry seals (CES) are designed to provide a reliable, watertight, and fume-tight seal where cables enter connection boxes, bulkheads, or other enclosures. Available in standard and threaded types, CES seals consist of a rigid nylon nut, an O-ring, and a heat-shrinkable molded body for standard applications, or a tapered national pipe thread (NPT) combined with a heat-shrinkable body for threaded-hole applications. They are ideal for cable penetration into panels, junction boxes, and sealed cabinets, offering strain relief and multi-leg breakout options. These seals are crucial for maintaining environmental integrity and ensuring reliable electrical connections in various industrial settings.
