Ancor 22-18 AWG Heat Shrink Butt Connector Jar, 250-Piece

The Ancor 22-18 AWG Heat Shrink Butt Connector Jar holds 250 sealed inline connectors in a reusable jar with a flip-top lid.

Twenty-two to 18 AWG is the smallest butt connector size, for instrument, sensor and control circuit splices. Using a 16-14 connector on this wire is the common error, and it leaves the conductor loose in the barrel no matter how firmly it is crimped.

Small wire also breaks more readily at a crimp than heavy wire does, so the heat shrink is doing structural work as well as sealing. The adhesive grips the insulation and adds strain relief, which is what stops an 18 gauge conductor fatiguing where it enters the terminal.

The clear jar keeps the connectors visible and organized, and the flip-top lid opens easily during work. Two hundred and fifty pieces suits a boat's spares or a service kit, since small-wire splices are frequent but individually minor. Explore more wire connectors and terminals.
