3M Ring Terminal for 18 AWG Wire

This 3M ring terminal accepts 18 AWG wire and provides a #8 stud connection for secure electrical bonding. The heat-shrink insulation seals the crimp joint against moisture and vibration. It is suited for automotive, marine and industrial wiring tasks that require a durable, insulated termination. The red insulation colour identifies the wire-range class at a glance.

Heat-shrink seal simplifies installation

The built-in heat-shrink tubing shrinks around the crimp when heated, eliminating separate sleeving or tape steps. This frees up bench time and reduces the number of components a technician must stock. The terminal crimps with standard tooling and fits a #8 mounting stud without adapters. Each pack contains 25 pieces for repeat jobs or inventory.

Rated for 600 V and 221 °F operation

Copper contact material carries current reliably within the 600 V maximum rating. The insulation withstands continuous temperatures up to 221 °F without degrading. CSA certification and UL listing confirm compliance with recognised safety standards. The 0.31 in tongue width keeps the connection compact inside panels or junction boxes.
