SC6-25 Ring Crimp Terminal Connector – Pure Copper Wire Lug

The SC6-25 Ring-type Crimp Terminal Connector is a heavy-duty electrical wire connector crafted from pure copper for maximum conductivity and long-lasting performance. Designed for secure, reliable crimped connections, this ring terminal is ideal for automotive wiring, marine electrical systems, home electrical projects, and industrial applications.

With its classic ring (lug) design, the SC6-25 slides easily onto bolt terminals and screw posts, creating a vibration-resistant, low-resistance connection that won't loosen over time. Compatible with 6 mm² wire (AWG 10) and 25 mm bolt hole diameter, this connector is a go-to choice for electricians, hobbyists, and DIY enthusiasts alike.

Frequently Asked Questions

Q: What wire size is the SC6-25 ring terminal compatible with?

A: The SC6-25 crimp ring terminal is designed for 6 mm² (approximately AWG 10) wire, with a 25 mm ring hole diameter for bolt or screw post connections.

Q: What is a crimp ring terminal and how do I install it?

A: A crimp ring terminal (also called a ring lug connector) is a type of electrical connector that you attach to the end of a wire by crimping the barrel onto the stripped wire using a crimping tool. Once crimped, the ring end slips over a bolt or screw terminal and is secured in place — creating a strong, low-resistance electrical connection. No soldering is required.

Q: Is the SC6-25 suitable for automotive and solar wiring applications?

A: Yes. The SC6-25 pure copper ring terminal is well-suited for a wide range of low-voltage applications including automotive wiring, battery connections, solar panel grounding, marine electrical systems, and general home or industrial wiring projects rated below 50V AC or 75V DC.

Q: Does this connector require any special tools?

A: You will need a crimping tool compatible with 6 mm² wire terminals. A ratchet crimping tool is recommended for best results, ensuring a secure and consistent crimp every time. No battery or power source is required for the connector itself.
