Half Storz male BSP fitting - Aluminium

What is a STORZ fitting? Definition and operation

The STORZ fitting is a symmetrical connection system used mainly in fire-fighting networks and professional hydraulic applications. Unlike traditional threaded fittings, STORZ fittings have no male/female direction: they are hermaphroditic, meaning that two identical fittings can be joined together.

Locking is achieved by a system of opposing claws (or lugs) that engage and lock together with a quarter-turn. This principle enables fast, reliable, tool-free connection, particularly suited to emergency situations.

Differences between STORZ and other fire fittings

In the field of fire and fluid transfer, several types of fittings coexist, each meeting specific standards and uses:

Threaded fittings: these need to be completely screwed on to ensure a watertight seal. Although they offer good mechanical resistance, they take longer to install and are less suited to rapid intervention.

Guillemin fittings (DSP/ARI): very widespread in France, these use a locking system with a rotating ring. They are high-performance but require more technical handling than STORZ symmetrical fittings.

Express fittings: mainly used for water networks and certain industrial applications, they are simple but less robust and less suited to intensive fire conditions.

STORZ fittings are easy to use, quick to connect and reliable. Its symmetrical nature eliminates assembly errors and considerably reduces intervention time. Today, it's a standard widely used in Europe and abroad, particularly in industrial environments and mobile equipment.

Why choose a STORZ fitting?

The STORZ fitting is particularly appreciated for applications requiring frequent, fast and secure connections. It enables

• Immediate tool-free installation
• Reduced connection errors
• Excellent mechanical resistance
• Compatibility with European standards
• Reliability under demanding conditions (construction sites, industry, emergency services)

Its robust design, often in aluminum or brass, guarantees a long service life even under intensive use.
