Wire Ferrules

Ferrules create compact, durable terminations on stranded wire before it enters a terminal block, screw clamp, control panel, relay, power supply, appliance, or audio connection. Choose by conductor size, ferrule length, insulation color, pack quantity, and the crimp profile required by the terminal geometry.

How to Choose and Use Wire Ferrules

Match conductor size

Choose the ferrule by the printed AWG or mm² rating, not by color alone. All strands should enter the metal sleeve without being cut or folded.

Match ferrule length

Use a barrel length that fits the stripped conductor and terminal-block opening. Strip only to the barrel length and keep insulation outside the conductive sleeve.

Match the crimp profile

Use a square or hex ferrule crimp profile sized for the conductor and terminal geometry. Pull-test the crimp before inserting it into the terminal block.
