Galvanized steel spanner wrench - for connections from DN50 to DN100

Reinforced wrench: an essential tool for tightening fire-fighting fittings

The reinforced wrench is an essential tool for tightening and loosening fittings used in fire-fighting networks and professional hydraulic installations. Designed for optimum leverage, it ensures reliable, tight and secure assembly of fittings subject to high mechanical stress.

Made from reinforced galvanized steel, this wrench offers excellent resistance to corrosion and repeated stress in the field. It is specifically designed for fittings from DN 50 to DN 100, covering the main diameters used in fire and industrial installations.

Operation and compatibility

The wrench is designed to fit claw-type fittings such as Guillemin (DSP/ARI) and certain symmetrical fittings used in fire-fighting systems. It enables high torque to be applied, while guaranteeing safe handling.

Its ergonomic shape makes it easy to hold and quick to use, even in difficult conditions. The reinforced version offers greater resistance to repeated stress and wear.

The difference between wrench wrenches and other tightening tools

Unlike standard tools such as open-end wrenches or adjustable wrenches, the tricoise w rench is specifically designed for fire connections. It enables :

• Perfect adaptation to fitting shapes
• High tightening torque without damaging equipment
• Increased safety during handling

It is therefore indispensable for guaranteeing the reliability of connections in pressurized networks or those subject to high operational constraints.
