Hellermann Tyton Pre-Insulated Terminal Blue Ring Lug M8 Hole

HellermannTyton Blue M8 Ring Terminal: Secure Double Grip Connection for 1.52.5 mm Cables

Engineered for High-Vibration Environments

The HellermannTyton Pre-Insulated Blue Ring Lug with M8 hole delivers a reliable, vibration-resistant connection for conductors ranging from 1.5 to 2.5 mm. Its double grip design features a specialised dual-crimp barrel that clamps both the conductor and the insulation, providing exceptional mechanical strength and electrical integrity. This makes it an ideal choice for automotive, marine, and industrial applications where movement and vibration are constant challenges.

Unlike generic single-crimp terminals, the double grip system significantly reduces the risk of wire pull-out and connection failure, ensuring long-term performance in demanding conditions. The terminal is manufactured using a precise three-piece process, combining a high-conductivity copper body with a durable PVC insulation sleeve, resulting in a component that meets rigorous quality standards.

Colour-Coded for Fast, Error-Free Installation

The blue vinyl insulation conforms to industry-standard colour coding for 1.52.5 mm conductors, allowing for quick visual identification during assembly and maintenance. This reduces the likelihood of mismatched terminal sizes, which can lead to poor crimps or overheating. The insulation is rated for continuous operation at +75 C, making it suitable for engine bays and other elevated-temperature locations.

With a maximum voltage rating of 600 V and a current capacity of 27 A, this terminal supports a wide range of low-voltage DC and AC circuits. It is particularly effective in 12 V, 24 V, and 48 V systems, offering versatility across automotive, solar, and auxiliary power setups. *Note typical de-rating factors apply when bundling or operating at elevated temperatures.

Key Features

• Double grip crimp secures both wire and insulation for superior vibration resistance
• Colour-coded blue insulation for instant size recognition (1.52.5 mm)
• M8 stud hole (8.4 mm) fits standard metric bolts for common busbar and stud connections
• Copper body with PVC sleeve ensures high conductivity and durable insulation
• +75 C temperature rating suitable for under-bonnet and enclosed installations
• 600 V max voltage and 27 A current rating for versatile circuit use
• Resealable packaging keeps terminals organised and protected on the job site

Built for Reliability in the Field

HellermannTytons pre-insulated ring terminals are trusted by professionals for their consistent quality and ease of use. The double grip design is especially valuable in mobile and off-grid applicationssuch as caravan wiring, marine electrical systems, and heavy equipmentwhere connections are subjected to constant shock and vibration. By gripping the insulation as well as the conductor, the terminal minimises stress at the crimp point, reducing the risk of fatigue failure over time.

The copper body provides low electrical resistance, minimising voltage drop and heat generation. Combined with the PVC insulation, which offers good chemical and abrasion resistance, this terminal is well suited to harsh environments. Whether you’re rewiring a trailer, installing a solar charge controller, or building a custom switch panel, this terminal helps ensure a professional, long-lasting connection.

Simple Installation with Standard Tools

These terminals are designed for use with common ratchet crimping tools (such as the HellermannTyton HYYT7), ensuring a gas-tight crimp every time. The funnel-shaped barrel entry guides the conductor smoothly into position, reducing installation time and the chance of stray strands. For best results, use a tool with the correct die profile for insulated terminals.
