Engineered with a \u003cstrong\u003edouble-grip crimp system\u003c\/strong\u003e, this terminal provides exceptional mechanical strength and electrical conductivity, making it ideal for use in automotive, marine, industrial, and control panel wiring where vibration and movement are constant concerns.\u003c\/p\u003e\n\u003cp\u003eUnlike standard single-crimp terminals that rely on a basic barrel compression, the double-grip design features a secondary crimp sleeve that independently secures the conductor insulation. This dual-point fixation significantly reduces the risk of wire pull-out and fatigue failure, ensuring consistent performance over the life of the installation. Whether you're wiring a fuse box, grounding a component, or terminating sensor leads, this terminal delivers the reliability professionals demand.\u003c\/p\u003e\n\u003ch3\u003eColour-Coded Vinyl Insulation for Instant Identification and Safety\u003c\/h3\u003e\n\u003cp\u003eThe terminal’s \u003cstrong\u003eblue vinyl insulation\u003c\/strong\u003e conforms to international colour-coding standards, allowing for immediate visual identification of the conductor size range (1.5–2.5 mm²). This not only speeds up assembly and maintenance but also reduces the likelihood of mismatched terminations that can lead to overheating or intermittent faults. The insulation is rated for continuous operation at \u003cstrong\u003e+75 °C\u003c\/strong\u003e, providing a safe touch-proof barrier while maintaining flexibility for easy installation.\u003c\/p\u003e\n\u003ch3\u003eThree-Piece Construction for Enhanced Durability\u003c\/h3\u003e\n\u003cp\u003eHellermann Tyton employs a \u003cstrong\u003ethree-piece manufacturing process\u003c\/strong\u003e that combines a high-conductivity copper body, a tin-plated finish for corrosion resistance, and a precisely moulded PVC insulation sleeve. This construction ensures low contact resistance, excellent thermal stability, and long-term protection against oxidation and environmental contaminants. The result is a terminal that performs reliably in both dry and humid conditions, including under-bonnet automotive environments and unsealed electrical enclosures.\u003c\/p\u003e\n\u003ch3\u003eKey Features at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-grip crimp design\u003c\/strong\u003e for superior vibration resistance and pull-out strength\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour-coded blue insulation\u003c\/strong\u003e for quick identification of 1.5–2.5 mm² conductors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM4 stud hole (4.3 mm)\u003c\/strong\u003e for secure fastening to standard metric studs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated up to 27 A and 600 V\u003c\/strong\u003e, suitable for a wide range of low-voltage applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating temperature +75 °C\u003c\/strong\u003e with PVC insulation for safe handling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplied in resealable packaging\u003c\/strong\u003e for convenient storage and inventory management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications Where Precision Matters\u003c\/h3\u003e\n\u003cp\u003eThis M4 ring terminal is engineered for use in \u003cstrong\u003e12 V, 24 V, and 48 V DC systems\u003c\/strong\u003e as well as mains-voltage control circuits, with a maximum voltage rating of 600 V.

Ensure the conductor is fully inserted into the barrel and that the crimp is centred over the wire strands. The double-grip design requires two distinct crimps: one on the conductor barrel and one on the insulation support sleeve. Always verify the crimp integrity with a pull test before energising the circuit.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNote: The 27 A rating represents the maximum current under ideal conditions. Typical de-rating factors such as ambient temperature, bundling, and duty cycle should be applied in accordance with local wiring regulations.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eSecure Your Connections Today\u003c\/h3\u003e\n\u003cp\u003eUpgrade your wiring projects with the \u003cstrong\u003eHellermann Tyton Pre-Insulated Blue Ring Lug M4\u003c\/strong\u003e.
