Create secure, permanent electrical connections with our Red Pre-Insulated Ring Terminals. Designed specifically for wire gauges between 0.5mm² and 1.5mm², these high-quality crimp connectors are an essential component for automotive wire harnesses, marine electricals, and general manufacturing. Supplied in a highly convenient pack of 100, they feature an electro-tin plated copper core for outstanding conductivity and durable PVC insulation to guarantee safe, reliable performance in demanding environments.

Exceptional Conductivity: The premium copper terminal core ensures optimal current flow, while the electro-tin plating prevents internal rust and oxidation.

Vibration-Proof Connection: The enclosed ring design allows a screw or threaded stud to pass completely through, meaning the connection cannot accidentally vibrate loose.

Industry Standard Colour Coding: The red PVC insulation instantly identifies the terminal as suitable for 0.5mm² to 1.5mm² wire sizes, speeding up your workflow.

Unbeatable Connection Security

When wiring critical components in a vehicle, a boat, or an industrial control panel, using a standard push-on spade terminal can sometimes be a risk if the machinery vibrates heavily. Ring terminals eliminate this risk entirely. Because a mounting screw, bolt, or threaded stud must pass directly through the centre of the terminal ring, it is physically impossible for the wire to disconnect unless the nut is completely removed. This makes them the ultimate, fail-safe choice for grounding wires, battery connections, and heavy-duty switchgear.

Premium Copper Core

A crimp connection is only as good as the metal inside it. These terminals are manufactured with a high-quality copper core to ensure minimal voltage drop and maximum electrical efficiency across your circuits. To protect the copper from long-term corrosion—especially in damp automotive or marine environments—the terminal is fully electro-tin plated. This plating acts as a robust barrier against oxidation, keeping your electrical systems running smoothly and preventing resistance build-up over time.

Safe, Colour-Coded Insulation

Safety and organization are paramount in any electrical build or repair. The tough PVC insulation sleeve completely covers the crimp barrel, protecting the vulnerable connection against accidental shorts and adding mechanical strain relief to the wire. Furthermore, the bright red colour adheres to international industry standards. Without needing to check a manual, any electrician instantly knows that a red terminal is the perfect fit for standard 0.5mm² to 1.5mm² gauge wiring.

Key Features

Protective PVC Insulation: The tough outer sleeve protects against accidental short circuits, insulates the crimped joint, and helps prevent the wire from fraying.
Flared Entry Point: The insulation features a slightly flared opening to allow for fast, snag-free wire insertion before crimping.
High Electrical Rating: Safely rated to handle voltages up to 600V and operating temperatures up to 75°C.
Multi-Sector Application: Perfectly suited for 12V/24V automotive electrics, switchgear panel building, grounding wires, and domestic appliance repair.
High-Volume Trade Pack: Supplied in a resealable bag of 100 pieces, offering fantastic value for auto-electricians, fabricators, and busy workshops.

Frequently Asked Questions

What tool do I need to crimp these terminals correctly?

You should use a dedicated ratcheting crimping tool designed specifically for pre-insulated terminals. You will need to place the terminal in the "Red" jaw/die. Avoid using standard pliers, as they will crush the insulation and fail to provide the uniform pressure needed for a secure, gas-tight electrical connection.

What do the different colours of crimp terminals mean?

In electrical crimps, colours denote the wire size capacity. Red is for 0.5-1.5mm² wire. Blue is typically for 1.5-2.5mm² wire, and Yellow is for thicker 4.0-6.0mm² wire.

Are these suitable for 240V mains wiring?

While the PVC insulation is technically rated up to 600V, crimp ring terminals are most commonly used in low-voltage DC applications (like automotive 12V/24V) or inside appliance control panels. If you are working with 240V AC mains circuitry, always ensure your application meets local electrical safety and building regulations.
