DESCRIPTION
Hellermann Tyton Blue M5 Ring Terminal: Precision-Engineered Double Grip Connection for Demanding Electrical Systems
Secure, Vibration-Resistant Termination for 1.5–2.5 mm² Conductors
The Hellermann Tyton Pre-Insulated Blue Ring Lug M5 Hole delivers a robust, maintenance-free electrical connection in environments where vibration and mechanical stress are constant challenges. Designed for 1.5–2.5 mm² copper conductors, this terminal combines a double-grip crimp profile with a colour-coded PVC insulation sleeve, ensuring both mechanical strength and straightforward identification during installation and inspection.
Unlike generic single-crimp terminals, the double-grip design secures both the conductor strands and the cable insulation in a single operation. This dual clamping action significantly reduces the risk of wire pull-out and fatigue failure, making it a preferred choice for automotive, marine, control panel, and industrial equipment applications where reliability is non-negotiable.
Three-Piece Construction for Consistent Performance
Each terminal is manufactured using a three-piece process: a high-conductivity copper barrel for low-resistance current transfer, a vinyl insulation sleeve for electrical isolation and mechanical protection, and a tin-plated ring tongue with a 5.3 mm stud hole. This layered construction ensures dimensional accuracy and repeatable crimp quality across high-volume production runs.
The copper barrel is annealed to optimise ductility, allowing it to conform tightly around individual conductor strands during crimping. This maximises contact area and minimises voltage drop, even under sustained load. The tin plating provides corrosion resistance, extending service life in humid or mildly corrosive atmospheres.
Colour-Coded Insulation for Fast, Error-Free Assembly
The blue PVC insulation conforms to international colour standards for 1.5–2.5 mm² conductors, enabling technicians to quickly select the correct terminal size without referencing charts. This reduces assembly time and the likelihood of mismatched crimps that can lead to overheating or intermittent connections.
The vinyl material is rated for continuous operation at +75 °C, making it suitable for engine compartments, machinery enclosures, and other elevated-temperature locations. The insulation also provides a degree of strain relief at the cable entry point, further enhancing vibration resistance.
Key Features
- Double-grip crimp profile secures conductor and insulation for superior vibration resistance
- Three-piece copper/PVC construction ensures consistent electrical and mechanical performance
- Blue colour coding for 1.5–2.5 mm² conductors simplifies selection and inspection
- 5.3 mm ring hole fits M5 studs (Approx. #10) for common terminal block and busbar connections
- 27 A maximum current rating and 600 V maximum voltage for low-voltage power and signal circuits
- Supplied in resealable bags to protect unused terminals from contamination and loss
Applications Where Reliability Matters
This M5 ring terminal is engineered for low-voltage DC and AC circuits up to 600 V, making it ideal for:
- Automotive wiring — fuse boxes, relays, earth points, and accessory circuits
- Marine electrical systems — navigation lights, bilge pumps, and switch panels
- Control panels and industrial machinery — sensor connections, solenoid valves, and terminal blocks
- Solar and battery installations — charge controllers, battery monitors, and small inverters
- DIY and prototyping — reliable connections for hobbyist projects and test setups
The double-grip feature is particularly valuable in mobile and high-vibration installations, where standard terminals may loosen over time. By crimping onto both the conductor and the insulation, this terminal maintains a gas-tight connection that resists fretting corrosion and thermal cycling effects.
*Note typical de-rating factors apply for continuous current near the 27 A maximum; ensure conductor size and ambient temperature are within design limits.

This policy applies to the original end-user purchaser of the product, as evidenced by a valid invoice or proof of purchase, and is not transferable without our written consent.
We warrant that the HellermannTyton products supplied by us are free from defects in materials and workmanship under normal use and service, subject to the terms and conditions below. This warranty applies only to the HellermannTyton product supplied and does not cover installation workmanship, system design, connected equipment, or other products not supplied by us.
The benefits given by this warranty are in addition to any other rights and remedies available under law. Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.

Installer Responsibilities and System Design
HellermannTyton products supplied by us are generally intended to be installed, crimped, terminated, insulated, protected, or incorporated into a broader electrical installation, vehicle, vessel, building, machine, switchboard, cable assembly, or other operating environment. We do not provide installation services unless expressly stated in writing, and we do not supervise or control installation practices carried out by installers, contractors, dealers, resellers, or end-users.
Once installed, the product may form only one component of a larger electrical or mechanical system. The installer, electrician, system designer, integrator, dealer, or end-user is responsible for ensuring that the selected product is suitable for the intended application and is installed correctly.
All HellermannTyton products must be installed and used in accordance with the product documentation, applicable Australian Standards, relevant electrical and industry standards, manufacturer specifications, and recognised industry best practice. The installer must ensure that the product is used within its specified ratings, including cable size, conductor type, voltage, current, temperature, insulation requirements, environmental exposure, mechanical loading and any applicable crimping or shrinking requirements.
Issues or damage arising from incorrect installation, incorrect product selection, poor system design, unsuitable tools, incorrect crimping, incompatible conductors, inadequate protection, inappropriate heat application, unsuitable mounting, or failure to follow instructions are not product defects and are not covered by this warranty.

Making a Warranty Claim
Important: If you suspect a fault with a HellermannTyton product supplied by us, do not remove or alter the product unless it is unsafe to leave it in place or unless authorised by us or the place of purchase. Premature removal, cutting, re-crimping, reheating, or alteration may prevent proper assessment and may limit warranty coverage.
- Contact the place of purchase: Warranty claims should be initiated through the authorised dealer, reseller, distributor, or place of purchase.
- Provide product information: The customer must provide proof of purchase, product model or part number, batch or identification details if available, a description of the issue, and photos or videos showing the product and installation.
- Provide installation details: We may request information such as cable size, conductor type, tool and die used, crimping method, heat source used, installation environment, connected equipment, load conditions, and applicable test results.
- Assessment and troubleshooting: The product and installation details may be assessed to determine whether the issue is likely to be a product defect or caused by installation, product selection, connected equipment, environment, misuse, or another excluded factor.
- Return for inspection: If the fault cannot be confirmed by correspondence, photos, or remote assessment, the product may need to be returned for inspection, testing, repair, or replacement assessment. Return instructions will be provided by the place of purchase or nominated assessment location.
- Evaluation and outcome: If the product is confirmed to have a defect covered by this warranty, an appropriate remedy will be provided. If the product is found not to be faulty, or the issue is caused by an excluded factor, the claim may be rejected.
Remedies Under Warranty
If a defect covered by this warranty is confirmed, we may, at our discretion and subject to Australian Consumer Law, provide one or more of the following remedies:
- repair;
