Bullet connectors are a small inline tube shape electrical connector which provide a reliable and efficient electrical connection, ensuring seamless current flow and minimal voltage drop. 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.

Bullet connectors are commonly used in wiring applications where reliable and efficient electrical connections are essential to prevent issues such as overheating, arcing, and electrical failures. With various sizes, styles, and configurations available, you can find the perfect bullet connector for your specific needs.

Our high-quality bullet connectors are perfect for a wide range of applications including automotive, marine, industrial and DIY projects. Bullet connectors are made from materials, such as copper, brass, and nylon, to ensure maximum conductivity and durability. They are designed to withstand harsh environments, including extreme temperatures, vibrations, and moisture, making them ideal for various applications.

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 shrink the insulation to the crimp for a tight, insulated and protected connection.

Applications

Bullet connectors are typically used in low-voltage DC applications, such as automotive wiring, marine wiring, industrial equipment, household appliances, and electronics. These connectors are utilised in applications where a repetitive connect and disconnect solution is required. The most common industries are:

Automation - for connecting wires in headlights, taillights, ignition systems, and audio systems, and provides a secure and easily detachable connection that allows for easy maintenance and repair
Audio speaker connection
Recording studios - secure and efficient connections between speakers, amplifiers, mixers
Electronics - for connecting wires in circuit boards, connectors, and other electronic components
Remote controlled (RC) vehicles - used in cars, boats, and airplanes, for connecting motor wires, and battery wires

Types:

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
