  • Ergonomic Design: Rounded corners and a smooth exterior finish over the abrasion-resistant plastisol insulation make Polaris connectors comfortable to grip
  • Removable Plugs: Each port and set screw comes with a secure plug to prevent debris from entering the insulated connector
  • Pre-filled Oxide Inhibitor: Both in-line ports come pre-filled with an oxide inhibitor gel to prevent corrosion and provide low-contact resistance
