Perma-Seal Heat Shrink & Crimp Butt Connectors

Molex's Perma-Seal waterproof adhesive butt connectors provide long-lasting, moisture-proof connections that withstand many corrosive fluids such as saltwater, hydraulic fluids and gasoline. The inner wall of the heat-shrinkable Perma-Seal NiAc sleeve is lined with a special hot-melt adhesive that is inert at room temperature. As the sleeve is heated, the adhesive melts and flows, filling any existing voids and creating a seal from the environment. To install, simply crimp onto the wire and heat with a heat gun or torch to shrink and seal. The NiAc insulation shrinks at a lower temperature (90°C) and up to 40% faster than polyolefin or nylon, saving installation costs and reducing the potential for wire insulation damage. The durable sleeve of Perma-Seal butt splice resists abrasion and cutting, maintaining the insulation and sealing properties even in the most hostile environments.


  • NiAc insulation shrinks 40% faster than nylon or polyolefin tubing.
  • Shrinks at a low temperature of 90°C (194°F).
  • Lined with hot melt adhesive.
  • See-through insulation allows for easy visual inspection.
  • Thicker insulation resists abrasion and cutting.
  • Funnel entry opening accommodates thick as well as thin wire insulation.
  • Insulation shrinks to less than half its original diameter.
  • Excellent chemical resistance.
