Cool-Seal Butt Connector

Cool-Seal Butt Connector null null

Cool-seal butt connectors are terminals that are used to mate, connect, or terminate a single wire. Cool-seal butt splices install within just a fraction of the time it takes to install comparable heat shrink terminals. By inserting two wires, the cool-seal adhesive molds around the wires, which forms a moisture-tight, secure electrical connection. No heating is required.


  • A heat-less, solderless terminal that utilizes an anaerobic sealant technology to prevent the ingress of moisture and air, within a nylon insulation that provides abrasion and puncture resistance.
  • Terminals install within just a fraction of the time it takes to install comparable heat shrink terminals.
  • Approximate 3 hour cure time for sealant.
  • 99.9% ETP copper terminal.
