Guillemin Symmetrical Half Coupling, Fire, with Lock with Male Threaded Socket without Jaws

The male Guillemin symmetrical half coupling in aluminium is a specific connection solution, designed without jaws (without guides) but incorporating a locking ring. This model is particularly sought after for equipping fixed installations or transport piping where locking must be controlled from the male side. Made in France, this coupling combines the lightness of aluminium with industrial machining precision, guaranteeing a flawless seal during critical fluid transfers.

An Integrated Lock for Enhanced Safety

The distinctive feature of this coupling lies in its 360° rotating locking ring, mounted on a male body without fixed jaws. This configuration allows the assembly to be mechanically locked by gripping the jaws of the opposite coupling. This technical specificity is highly sought after in the liquid bulk transport sector (particularly petroleum products) and pulverulent materials, where locking security is paramount to avoid any accidental disconnection under pressure or due to vibration.

BSP Thread: Standardisation and Versatility

Equipped with a male BSP (British Standard Pipe) thread, this coupling integrates naturally with a wide range of equipment: sector valves, pump bodies, industrial manifolds or tank outlets. Its French manufacture ensures strict compliance with thread tolerances, enabling a durable and leak-proof installation. Its versatility opens the doors to many sectors such as petrochemical and pharmaceutical industries, agricultural irrigation, steel plants and heavy construction sites.

Assembly Tips and Implementation

For the threaded part, the use of a suitable sealant (PTFE tape or industrial paste) is recommended to ensure the connection with the tapped support. For the symmetrical connection, present this half coupling facing a model fitted with jaws. Make sure the NBR seals are clean and pressed firmly against each other. Operate the lock manually to secure the joint. For intensive use or under high pressure, it is advisable to finalise tightening with a Guillemin wrench to secure the lock.
