Hellermann Tyton Pre-Insulated Terminal Yellow Ring Lug M8 Hole

Hellermann Tyton Double Grip Pre-Insulated Yellow Ring Lug for M8 Studs

Reliable High-Vibration Connections for 4.0-6.0 mm² Cable

The Hellermann Tyton Pre-Insulated Yellow Ring Lug is engineered for secure, long-lasting electrical connections in demanding environments. Designed for 4.0-6.0 mm² conductors, this lug features a double grip crimp that provides exceptional mechanical strength and electrical conductivity, making it ideal for applications subject to constant vibration and movement.

Whether you're wiring a 12V automotive system, a 24V or 48V auxiliary circuit, or industrial control panels, this terminal ensures a stable connection. The M8 hole (8.4 mm) fits standard stud sizes, while the colour-coded yellow vinyl insulation allows for instant identification of the correct cable size, reducing installation errors and improving workflow efficiency.

Engineered for Tough Conditions

Unlike generic terminals, the Hellermann Tyton Double Grip series uses a three-piece manufacturing process that integrates the copper barrel, insulation, and double crimp sleeve into a single robust unit. This design minimises the risk of connection failure due to vibration, thermal cycling, or mechanical stress—common issues in automotive, marine, and industrial settings.

The vinyl insulation is rated for continuous operation up to +75 °C, providing reliable performance in engine bays and other high-temperature areas. With a maximum current rating of 48 A and a voltage rating of 600 V, this lug handles substantial power demands while maintaining safety margins. Note: typical de-rating factors apply based on installation conditions.

Key Features

• Double grip crimp for superior vibration resistance and pull-out strength
• Colour-coded yellow insulation for quick, error-free cable size identification
• Three-piece construction ensures consistent crimp quality and durability
• Copper barrel with tin plating for excellent conductivity and corrosion resistance
• Wide operating temperature range up to +75 °C for under-bonnet and industrial use
• M8 stud hole (8.4 mm) compatible with common terminal blocks and busbars

Applications Where Reliability Matters

This ring lug is a proven choice for professionals who cannot afford connection failures. Typical uses include:

• Automotive wiring: battery terminals, starter motors, alternators, and earth points
• Marine and RV systems: 12V/24V DC circuits exposed to constant motion and moisture
• Industrial machinery: control panels, motor connections, and equipment subject to vibration
• Renewable energy: solar panel combiner boxes and battery interconnects

By choosing a pre-insulated terminal from Hellermann Tyton, you reduce the risk of loose connections, overheating, and intermittent faults that can lead to costly downtime or safety hazards. The double grip design is particularly effective in preventing wire pull-out, a common failure point in single-crimp lugs.

Installation Made Simple

For best results, use the recommended Hellermann Tyton HYYT7 crimping tool to achieve a precise, gas-tight crimp. The transparent insulation allows visual inspection of the crimp, ensuring quality control before the connection is put into service. Always match the lug to the correct conductor size (4.0-6.0 mm²) and strip length to maximise performance.
