Bullet Connectors

A bullet crimp connector is a small inline tube shape electrical connector. At the termination end, there is a hollow female section for the insertion of stranded or solid wire. At the connection end, there is a male bullet-shaped head. Bullet crimp connectors are also available as double female inline crimp terminals.

What do bullet connectors do?

Bullet connectors are solderless electrical connections used to connect stranded or solid wire. Bullet crimps are easy to use, they simply push in and snap together making a simple reliable connection.

How do I install bullet connectors?

Bullet connectors are effortless to install. The majority of bullet connectors are designed to be crimped onto a cable and then finished off by using heat to heat shrink the insulation to the crimp for a tight, insulated and protected connection.


These connectors are utilised in applications where a repetitive connect and disconnect solution is required. The most common industries are:

  • Automation

  • Audio speaker connection

  • Theatre

  • Recording studios


Bullet connectors are available in a wide variety of bullet diameters and wire sizes. Wire size is quoted in CSA (cross sectional area) or AWG (American wire gauge). Insulated crimps are often colour coded. The colour of the insulation is used to denote the wire size. The most common are:

  • Red 0.5 mm² to 1.5 mm²

  • Blue 1.5 mm² to 2.5 mm²

  • Yellow 2.5 mm² to 6 mm²
