EM Group Tubular Ring Terminal 25mm² M6 Tinned Copper

The EM Group tubular ring terminal is a high-performance electrical component engineered for the secure termination of 25mm² conductors. Designed with an M6 stud hole, this terminal provides a stable and reliable connection point for various electrical systems. Constructed from premium tinned copper, it offers exceptional electrical conductivity while providing a robust barrier against oxidation and environmental corrosion, ensuring long-term performance in demanding conditions.

Advantages

This tubular ring terminal stands out due to its high-quality material composition, which minimizes electrical resistance and maximizes current flow efficiency. The tinned copper finish provides superior protection against rust and corrosion, making it suitable for use in environments where moisture or chemical exposure might be a concern. Its tubular design allows for a precise and firm crimp, creating a permanent mechanical and electrical bond that resists vibration and thermal expansion, thereby reducing the risk of connection failure over time.

Suitable for

• Professional electrical panel wiring
• Power distribution systems
• Grounding and earthing applications
• Industrial machinery connections
• Automotive and marine electrical installations

When it may not be suitable

This terminal is specifically designed for 25mm² conductors and an M6 stud size. It is not suitable for cables with different cross-sections, as an improper fit will result in a weak connection and potential overheating. Additionally, it should not be used in applications requiring stud sizes other than M6, as the physical interface will not be compatible.

Key specifications

• Conductor cross-section: 25mm²
• Stud hole diameter: M6
• Material: Tinned copper
• Terminal type: Tubular ring

How to use

To install the terminal, first strip the insulation from the end of the 25mm² conductor to the appropriate length required for the barrel. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool specifically calibrated for tubular terminals to compress the barrel onto the wire, ensuring a tight, gas-tight connection. Once crimped, place the ring over the M6 stud and secure it firmly with a nut and washer to ensure optimal contact.

What to consider before purchase

• Verify that your cable cross-section is exactly 25mm².
• Ensure the mounting surface has an M6 threaded stud.
• Check that your crimping tool is compatible with tubular copper terminals.
• Confirm the environmental conditions to ensure tinned copper is appropriate for your specific application.

Usage recommendations

Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid over-tightening the nut on the M6 stud to prevent damage to the terminal or the mounting surface. Regularly inspect connections in high-vibration environments to ensure they remain secure.
