Conversions Tech Non-Insulated Copper Ring Terminals — Tin-Plated SC Series (4 AWG – 10 AWG, 20 PCS)
The Conversions Tech SC-Series Non-Insulated Copper Ring Terminals are precision-engineered compression lugs designed for high-performance electrical terminations. Manufactured from seamless, tin-plated copper tubing, these terminals deliver maximum conductivity, corrosion resistance, and mechanical strength. Ideal for automotive, solar, industrial, and marine wiring, each ring terminal ensures secure, low-resistance connections under heavy load conditions.
Key Features and Advantages
- High-Conductivity Copper: Made from 99.9% electrolytic copper for optimal current transfer and minimal voltage drop.
- Tin-Plated Finish: Provides long-term corrosion protection and enhanced surface conductivity for crimped connections.
- Seamless Tubular Barrel: One-piece barrel construction ensures consistent compression and improved mechanical pull strength.
- Non-Insulated Design: Ideal for applications requiring direct crimping with custom insulation or heat-shrink protection.
- Universal SC-Series Fit: Compatible with standard SC10-6, SC10-8, SC16-8, and SC25-6 configurations.
- Wide Wire Range: Suitable for 4 AWG to 10 AWG conductors in UL-listed installations.
- High Voltage Rating: Rated up to 35 kV for use in power distribution, control panels, and heavy-duty equipment.
- Heat & Vibration Resistant: Maintains mechanical integrity and contact stability under demanding environmental conditions.
- RoHS Compliant: Free from lead, mercury, and other restricted substances.

Frequently Asked Questions (FAQs)
1. What material are these terminals made from?
They are manufactured from high-conductivity electrolytic copper with a protective tin-plated surface for corrosion resistance.
2. What wire sizes do these terminals support?
They are designed to fit conductors ranging from 4 AWG to 10 AWG, depending on the specific SC model.
3. Are these terminals insulated?
No. They are non-insulated to allow for heat-shrink or other custom insulation methods after crimping.
4. What voltage are they rated for?
The SC-Series is rated for up to 35 kV, suitable for high-voltage and heavy-current electrical connections.
5. Are they compliant with UL or CSA standards?
Yes. They meet UL and CSA temperature ratings (90 °C) and are RoHS compliant for environmental safety.
6. What’s included in the package?
Each pack contains 20 pieces of assorted tin-plated copper ring terminals (SC10-6, SC10-8, SC16-8, and SC25-6).
7. Can they be used for both stranded and solid wire?
Yes. These terminals are compatible with both stranded and solid copper conductors for crimp-type terminations.
8. What crimping tools should I use?
Use a standard hex or hydraulic crimping tool designed for SC-series copper lugs to achieve a reliable mechanical and electrical bond.
9. Are they suitable for marine or outdoor use?
Yes. The tin plating provides excellent corrosion resistance, making them suitable for marine, RV, and outdoor electrical systems.
10. Who manufactures these terminals?
All SC-Series copper ring terminals are designed and tested by Conversions Tech for professional electrical and industrial applications.
