Wire disconnects for 14 to 16 AWG

This pack supplies 50 blue nylon quick-disconnect terminals rated for 14 to 16 AWG copper wire. Each terminal uses a butted-seam crimp barrel with full insulation coverage and a 0.25 in tab width. The connectors suit automotive and industrial wiring jobs that need a secure, removable joint.

Rated for 600 V and 221 °F continuous

Tin-plated copper contacts carry up to 600 V while the nylon housing withstands 221 °F maximum operating temperature. The crimp termination and butted seam maintain mechanical strength and electrical continuity under sustained load and vibration. RoHS compliance confirms the materials meet restricted-substance requirements.

Verify wire gauge and tab dimensions first

Confirm the existing harness uses 14 to 16 AWG conductors and 0.25 in wide tabs with 0.032 in thickness before ordering. The blue colour coding matches the 14 to 16 AWG range, so a different gauge will need a different terminal series. No UL 94 flammability rating applies to this insulation.
