Guillemin Symmetric Half Coupling, Fire, with Locking Jaw, Male Threaded Socket

The male threaded Guillemin symmetric half coupling is an essential standard for the quick connection of industrial pipework. This model, fitted with a security lock (jaws), enables a robust and instant mechanical connection. Made in France, this aluminium coupling combines lightness and strength, offering a durable solution for demanding professionals who wish to equip their fixed installations or transfer vehicles.

Secure Locking and Versatility of Use

This "fire" coupling stands out thanks to its 360° rotating locking ring, which controls the jaws (guides) for a firm and tight coupling with the opposing half coupling. Its symmetric design allows connection without gender distinction, optimising emergency interventions. Usable in both suction and discharge, it supports the passage of various fluids, whether liquids or bulk powdery materials. The aluminium used ensures easy handling without sacrificing the structural strength required in industrial environments.

BSP Gas Thread: Universal Integration

Fitted with a male BSP (Gas Thread) connection, this coupling installs directly onto your pump outlets, valves, manifolds or tanks. The quality of French machining guarantees perfect thread conformity, ensuring optimal sealing on the fixed part of your installation. Its fields of application are extremely wide: fire fighting, petroleum, chemical, petrochemical and pharmaceutical industries. It is also a valuable asset in the construction sector, steelworks and for intensive agricultural irrigation.

Assembly Tips and Maintenance

For the threaded part, we recommend using an appropriate sealing product (PTFE tape or industrial sealing paste) to secure the connection with the tapped support. For the symmetric connection, present the two half couplings face to face, ensure that the NBR seals (factory fitted) are clean and in proper contact. Engage the lock manually to join the jaws together. For high-pressure applications or those subject to vibrations, it is advisable to finalise tightening with a suitable Guillemin wrench.
