Symmetrical Half-Coupling without Lock Aluminium | Grooved Ferrule

The Guillemin symmetrical half-coupling with grooved ferrule, in the without jaws (lockless) version, is an essential technical component for fluid transfer configurations where locking is already provided by the opposing coupling. Made from high-quality aluminium, this coupling is designed to be permanently crimped onto flexible hoses. Proudly made in France, it embodies national industrial excellence, offering robustness and fitting precision indispensable for the most demanding professional applications.

French manufacturing for unrivalled reliability

This symmetrical coupling, produced in our French factories, benefits from rigorous quality control and a selection of aluminium offering optimal resistance to corrosion and impact. By choosing a product made in France, you ensure perfect compliance with European safety requirements. Its lightness, combined with its robustness, makes it the preferred choice for firefighting, petroleum industries and chemical sectors where every component must meet critical performance standards.

Crimping versatility and multiple applications

The grooved ferrule of this coupling has been designed to offer maximum grip when crimped onto technical hoses. It is compatible with a wide range of fastening systems: drawn skirts for a clean industrial finish, notched skirts for enhanced hold, or trunnion clamps and banding straps for easier maintenance. This adaptability allows its use in fields as varied as construction, steelworks, or the transport of bulk liquids and powdered materials.

Use in suction and discharge

Thanks to its perfectly machined symmetrical design, this lockless coupling ensures a complete seal, whether used in suction or discharge. It is particularly recommended for agricultural irrigation networks and industrial maintenance where speed of connection is an asset. Its lack of integrated locking mechanism provides a weight saving and reduced bulk, while coupling perfectly with any standard Guillemin coupling fitted with a lock.

Assembly and safety advice

For optimal assembly, ensure that the grooved ferrule is correctly inserted into the hose before proceeding with crimping. Once crimped, present the half-coupling facing a model fitted with a lock. Make sure the seals are clean and pressed against each other. Turn the ring of the opposing coupling to lock the assembly. For installations under high pressure, the use of a Guillemin wrench is strongly recommended to finalise tightening and ensure the safety of operators and equipment.
