Perma-Seal Heat Shrink & Crimp Step-Down Butt Connectors

Molex Perma-Seal Waterproof Adhesive Step-Down Butt Connectors: Long-Lasting, Moisture-Proof Connections at Del City

Del City offers Molex's Perma-Seal waterproof adhesive step-down butt connectors, designed to provide moisture-proof, corrosion-resistant connections that withstand exposure to harsh fluids such as saltwater, hydraulic fluids, and gasoline. These connectors are ideal for automotive, marine, and industrial applications where reliable and durable connections are essential. The step-down design allows for the secure connection of two wires with different gauge sizes, making it versatile for various wiring configurations.

The heat-shrinkable NiAc sleeve features a special hot-melt adhesive lining that remains inert at room temperature but activates as the sleeve is heated. This adhesive melts and flows, filling voids and creating a complete environmental seal around the terminal, protecting the connection from moisture, dirt, and other contaminants. Installation is simple—crimp the connector onto the wires and use a heat gun or torch to shrink and seal the connection.

NiAc insulation used in these connectors shrinks at a lower temperature of 90°C (194°F), and up to 40% faster than traditional polyolefin or nylon insulation, reducing installation time and minimizing the risk of wire insulation damage. This durable heat-shrink tubing resists abrasion and cutting, maintaining its insulation and sealing properties even in the most hostile environments.

The see-through insulation allows for easy visual inspection of the wire connection, ensuring a secure installation, while the funnel entry opening accommodates wires with both thick and thin insulation, making it easy to handle varying wire types. The insulation shrinks to less than half its original diameter, providing a tight, secure fit that offers excellent chemical resistance.
