Frequently asked questions

What wire size do these connectors fit?

They are intended for 12-10 AWG wire (4–6 mm²). Select the connector size that matches the wire.

How many connectors are included?

The pack contains 500 yellow butt connectors.

Do I need to solder the connection?

No. These are crimp butt connectors. Crimp the copper barrel, then shrink the insulation with a heat gun.

What tools do I need?

Use a wire stripper, a suitable crimping tool and a heat gun. Work only on de-energized wiring.

What does the heat shrink insulation do?

When correctly heated, it insulates the splice and helps seal it against moisture. The finished connection depends on correct wire selection and installation.

Are these ring or spade terminals?

No. These butt connectors join two wire ends in line. They do not attach a wire to a stud or blade terminal.
