Aluminium Guillemin Fitting with Annulated Shank | Made in France

The Guillemin symmetric half-coupling with annulated shank, made from high-quality aluminium, is the essential standard for demanding fluid transfer operations. Better known as a fire hose coupling, this annulated shank model is specifically designed to be crimped onto flexible hoses, ensuring an undeformable and secure connection. Proudly made in France, this fitting combines industrial precision and robustness to meet the strictest safety standards in the European market.

French Manufacturing for Extreme Versatility

This symmetric coupling stands out for its ability to operate in both suction and discharge applications. Its French manufacturing guarantees optimal aluminium quality, offering an excellent weight-to-strength ratio. This versatility allows it to be used in critical fields such as firefighting, petrochemical, chemical and pharmaceutical industries, as well as in the construction and agricultural sectors. It is perfectly suited for liquid bulk transport as well as pulverulent materials, ensuring smooth flow without pressure loss.

Crimping Systems and Compatibility

The annulated shank of this Guillemin half-coupling is designed to accept different fastening systems according to your pressure and safety requirements. It can be fitted with drawn ferrules for an industrial finish, notched ferrules for enhanced grip, or more conventionally with trunnion clamps or banding. This adaptability makes it a universal component for maintenance and irrigation, capable of fitting onto any technical flexible hose while maintaining a perfect seal under stress.

Assembly Tips and Installation

To ensure the longevity of your installations and a flawless seal, we recommend a rigorous connection protocol. Present the two Guillemin half-couplings face to face, ensuring alignment of the gaskets. During assembly, the gaskets must be perfectly pressed against each other. Then rotate the rings (locking collars) by hand until the guides click into place. To finalise the operation and secure the connection against vibrations or water hammer, always use an appropriate Guillemin wrench for optimal tightening.

Industry Sectors and Industrial Reliability

Thanks to its symmetric design, this coupling allows quick connection without gender distinction (male/female), which is a major advantage in emergency situations or intensive maintenance. It is found in steelworks, petroleum logistics centres and agricultural operations for irrigation. Its resistance to corrosion and its lightweight nature make this French-made fitting the preferred choice of professionals requiring constant reliability for the transport of non-aggressive chemicals and liquid bulk.
