Break-away Couplers, also known as Emergency Release Couplers, are fundamental components in fluid transfer systems, designed to prevent hazardous spills and protect equipment from damage in the event of accidental drive-away or brake failure during loading operations. These devices are commonly used in locations like fuel and chemical terminals, distilleries, and gas terminals where fluid transfer lines could be at risk. They operate by separating into two halves when exposed to certain forces, causing valves to shut off and effectively stop the flow of fluid. This mechanism ensures safety and mitigates risks associated with human errors.
Assentech goes beyond supply by providing expert training in the maintenance of these critical safety units. Our training ensures that every coupler remains safe, reliable, and precisely calibrated to its specified breakload, with the correct torque settings applied. We don’t just train, we give you documented, evidential proof of competence, enabling you to demonstrate that your technicians are factory-trained and fully qualified to maintain these units. This strengthens compliance, builds customer confidence, and safeguards performance throughout the product’s life
Types of Break-away Couplers we Supply
- Non-Cryogenic Industrial Break-away Coupling : With their unique design that activates under a bending moment at angles from zero to 90 degrees, offer unparalleled versatility and adaptability for all industrial product transfer installations due to their infinite material selection.
- Cryogenic Industrial Break-away Coupling : Featuring an innovative design that activates under a bending moment from zero to 90 degrees, offer proven reliability and versatility for a wide range of applications, including LNG transfer solutions and handling of substances like Liquid Oxygen, Ethylene, and Ethane, even under extreme temperatures down to -196°C (-320°F).
- Non-Cryogenic Emergency Release Coupling: Employ Flip-Flap technology for controlled separation of the halves using cable, hydraulic, or dual release systems, reducing stress on media transfer systems, with wide usage in LPG, fuel, and chemical transfer installations, offering optimal flow rate and closure solutions, with the choice of release method tailored to individual needs for enhanced safety and reliability.
- Cryogenic Emergency Release Coupling: Leverage Flip-Flap technology for controlled activation through cable, hydraulic, or dual release systems, providing a safe, reliable solution for cryogenic transfer applications such as bunkering, refuelling, and loading arms, with comprehensive on-site testing for the highest safety standards and versatile installation methods tailored to suit specific client requirements.


Certification & Documentation Package
Please note certification is available but must be requested at RFQ stage to understand cost and lead time—this provides full clarity and avoids delays when your order is processed with the factory.
-
- Material Certification and Traceability
- 3.1 certification – Confirms the material is tested, traceable to the batch, and meets specification.
- 3.2 certification – Independent third-party validated; used where the highest level of assurance is required for critical safety parts.
- Certificates
- Certificate of Conformity – Confirms the equipment supplied meets contractual and technical requirements.
- Hydrostatic / pressure test certificates – Proves the coupler has been pressure tested for safe performance.
- ATEX & Hazardous Area Compliance
- ATEX certificates available – Demonstrates suitability for explosive or hazardous atmospheres.
- Additional Standards
- PED – Compliance with the Pressure Equipment Directive for safety of pressurised systems.
- ISO 9001 & ISO 14001 – Assurance of certified quality and environmental management at the factory.
- Specialist Materials
- Media compatibility check – Ensures housings and seals are suited to the intended media.
- Options for corrosive/toxic/flammable media – Reduces risk of leakage and extends service life.
- Comprehensive Certification Package
- Consolidated documentation pack – Simplifies customer assurance with all certificates in one place.
- Important: Some elements (e.g., 3.2, CoC, ATEX) must be requested at quotation stage to ensure inclusion at order stage.
- Material Certification and Traceability
