Product Description

This cable penetrator is a simple solution to waterproofing your robot. It’s basically a bolt with a hole that the thruster cable can be glued (potted) into to provide a waterproof connection through watertight enclosures, boxes, panels, etc.

We primarily recommend the WetLink Thixotropic Potting Compound, which can be applied in one step and provides a depth rating up to 1000 meters. Alternatively, we recommend Loctite Marine Epoxy and the Potting Kit to complete assembly.


  • Anodized aluminum construction for corrosion resistance and high strength
  • Captive O-ring face seal that works on any smooth surface
  • Wrench flats for easy tightening
  • Multiple inner diameters to secure the cable jacket but leave room for potting compound
  • Works for cables smaller than 6mm as well


  • 1 x Cable Penetrator Bolt (for 6mm cable)
  • 1 x Cable Penetrator Nut
