Hellermann Tyton Pre-Insulated Red Ring Lug: Reliable Double Grip Termination for M10 Studs

Engineered for Secure Connections in High-Vibration Environments

The Hellermann Tyton Pre-Insulated Red Ring Lug is a professional-grade terminal designed to deliver consistent electrical performance in demanding applications. With its double grip crimp design, this lug provides superior mechanical retention and electrical contact, making it an excellent choice for automotive, marine, and industrial wiring where vibration and movement are common.

Manufactured using a three-piece process, the terminal combines a copper body for optimal conductivity with a durable PVC insulation sleeve. The colour-coded red vinyl insulation allows quick identification of the 0.5–1.5 mm² conductor size range, streamlining installation and reducing the risk of mismatched connections. Rated for up to 19 A maximum current and 600 V maximum voltage, this ring lug is suitable for a wide range of low-voltage DC and AC circuits, including 12 V, 24 V, and 48 V systems.

Note: The stated 19 A rating is a maximum value; typical de-rating factors apply based on installation conditions, ambient temperature, and bundling.

Key Features

• Double grip crimp ensures reliable contact in high-vibration settings
• Three-piece construction with copper body and PVC insulation for durability
• Colour-coded red insulation for fast, accurate size identification
• M10 stud hole (10.5 mm diameter) fits standard metric fasteners
• Wide operating temperature range up to +75 °C for versatile use
• RoHS compliant materials for environmental responsibility

Built for Demanding Electrical Systems

Unlike generic terminals that may loosen under stress, the double grip mechanism of this Hellermann Tyton lug crimps onto both the conductor and the insulation, providing strain relief and reducing the risk of wire pull-out. This feature is particularly valuable in automotive wiring harnesses, marine electrical panels, and industrial control cabinets where reliability is critical.

The vinyl insulation not only protects against accidental short circuits but also resists common automotive fluids and mild chemicals, extending the service life of the connection. The copper conductor offers low resistance, minimising voltage drop and heat generation at the termination point.

Applications

This red ring lug is ideal for terminating stranded copper conductors between 0.5 mm² and 1.5 mm² onto M10 studs or bolts. Typical uses include:

• Automotive earth and power distribution points
• Marine battery and switch panel connections
• Solar charge controller and inverter wiring
• Industrial machinery and control systems
• DIY electrical projects requiring secure ring terminations
