  • Product typeElectrical Connectors
  • Crimp termination creates secure joints
  • Yellow nylon insulation identifies 10 AWG maximum wire size
  • Heat-shrink tubing seals out moisture and vibration
  • CSA certified and UL listed for 600 V service
  • Pack of 50 connectors covers multiple repair jobs

10 AWG Crimp Connectors

This pack contains fifty yellow nylon butt splice connectors rated for 10 AWG maximum wire size. They accept conductors down to 12 AWG and provide a crimp termination with an overlapped seam. The copper contacts are insulated with heat-shrink material that activates during installation.

CSA and UL Listed

Each connector carries CSA certification and UL listing for 600 V maximum voltage. RoHS compliance confirms restricted substance limits. The 1.75 in overall length and 0.142 in barrel inside diameter fit standard automotive and marine wiring channels without modification.

Heat Shrink Durability

The heat-shrink insulation seals against moisture and vibration once crimped and heated. Rated to 221 degrees F maximum operating temperature, the nylon sleeve resists degradation under sustained engine-bay heat. The overlapped seam maintains mechanical grip during long-term thermal cycling.

Questions about this item

At what temperature does the yellow nylon insulation reach its 221 °F rating during a long crimped run?

The butt splice is rated for a maximum operating temperature of 221 °F, so sustained current that pushes the connector beyond that point would exceed its thermal limit.

How much heat does each 10 AWG crimp joint add when the circuit runs at 600 V all day?

Each connector is UL listed and CSA certified for 600 V, and the copper barrel with overlapped seam is designed to minimise resistive heating at the rated 10 AWG maximum.

Which crimp tool and 12–10 AWG wire must I already have to install these 50 yellow butt splices?

You need a crimp tool suited to 12–10 AWG terminals and stranded copper wire between 12 AWG minimum and 10 AWG maximum to match the 0.142 in barrel inside diameter.
