  • TypeElectrical Connectors
  • Blue vinyl insulation identifies 14 AWG wire size
  • Tin-plated copper barrel resists corrosion
  • Brazed barrel withstands vibration and pull-out
  • Crimp termination installs quickly with standard tools
  • 100-piece pack suits volume wiring jobs

3M 14 AWG Ring Terminals 100 Pack

These vinyl-insulated ring terminals accept 14 to 16 AWG wire and a #6 stud. The copper barrel with tin finish is brazed for a secure crimp connection. They suit automotive, marine and general low-voltage wiring jobs where a reliable ring lug is required.

Temperature Range and Voltage Rating

The terminals operate from -40 °F to 221 °F and carry a 600 V rating with a 1 000 V maximum. Vinyl insulation resists cracking in cold conditions and softening in heat. No active cooling or derating is needed for normal crimped installations.

Crimp Tooling and Space Considerations

A standard crimp tool for 14 to 16 AWG barrels completes the termination. The 0.25 in tongue width and 0.8 in overall length keep the footprint small in terminal blocks or bus bars. The 100-piece pack provides enough terminals for multiple circuits without individual packaging waste.

Highlights

  • Tin-plated copper barrel resists corrosion
  • Brazed barrel withstands vibration and pull-out
  • Crimp termination installs quickly with standard tools
  • 100-piece pack suits volume wiring jobs

Questions about this item

How do I crimp the 3M MVU14-6R/SX ring terminal onto 14 AWG wire and what step is often missed?

Strip the wire to expose the conductor, insert it fully into the brazed barrel, then compress with a ratchet crimp tool sized for 14 AWG; the step often missed is verifying the wire reaches the barrel inspection window before crimping.

What maintenance or replacement will the vinyl-insulated terminals need over time?

Inspect the blue vinyl insulation for cracking or hardening after exposure to temperatures near the 221 °F maximum; replace any terminal showing discoloured copper or brittle insulation to maintain a reliable 600 V connection.

What limit appears first when the connection runs continuously at high current?

The 221 °F maximum operating temperature of the vinyl insulation is typically reached before the copper barrel or tin plating degrades, so sustained loads must stay within the terminal's thermal rating.
