Half symmetrical fitting Guillemin, firefighter, no female threaded socket lock

The Guillemin Symmetrical Female Screw-On Half Coupling, in the non-latched version (without jaws), is a standardised connection designed to be mounted on male threaded outlets or fixed equipment. Made in France, this fitting benefits from optimal machining precision, guaranteeing a reliable and secure connection over the long term. Its symmetrical design allows for quick coupling with any half-fitting equipped with a lock, facilitating transfer operations in the most demanding sectors.

BSP tapping for full industrial compatibility

This fitting has a "Gas Pitch" (BSP) thread, the European standard for industrial and agricultural piping. This feature allows direct installation on valves, tank outlets or transfer pumps. In the lockless version, it is particularly appreciated for its simplicity and small size, while ensuring a perfect seal once mated. The mastery of French manufacturing ensures strict compliance with thread tolerances, thus avoiding assembly problems and pressure leaks.

Versatility of use in suction and discharge

Designed to withstand intensive conditions of use, this symmetrical fitting operates with the same efficiency in suction as in discharge. Its fields of intervention are extremely broad: firefighting, petroleum, chemical and petrochemical industries, or the pharmaceutical sector. In the stainless steel version, it adapts perfectly to the requirements of the food and sugar industry. It is also the preferred solution for the transport of liquid and powdery bulk in steel mills, construction and industrial maintenance.

Assembly and sealing advice

For the installation of the threaded part, we recommend the use of an appropriate sealant (PTFE tape, filasse or anaerobic resin) depending on the nature of the fluid being transported. For the symmetrical connection, present this half-fitting without a lock in front of a half-fitting with locking jaws. Make sure the NBR seals are clean and in good contact. Engage the jaws by turning the lock on the opposite fitting. For maximum safety, especially during high-pressure transfers, finalize the tightening with a suitable Guillemin key.

Technical characteristics

French reliability at the service of industry

Choosing this fitting made in France means choosing a durable product, machined according to rigorous quality standards. With no moving parts, this "lockless" version simplifies maintenance and limits mechanical wear, while providing rock-solid strength for agriculture, irrigation and construction. Whether for a pumping station or an industrial manifold, this half-fitting guarantees consistent performance, even after many connection cycles.
