Storzy Coupling Wrench – Lightweight, Super Strong & Fire Suit-Friendly
The solution for damaged firefighting gear caused by steel coupling wrenches!

The Storzy coupling wrench is specially developed for connecting fire hoses with a Storz coupling. It is an alternative to traditional steel wrenches, which often damage firefighting suits and junior firefighter gear. This innovative fire service tool combines ease of use with durability and safety.

Optimal Fit

The Storzy is not a universal wrench – and that is exactly its strength. While many wrenches are designed to “fit everything” but never really fit well, the Storzy has been specifically engineered for real-life firefighting operations. Almost all Storz couplings used in the fire service involve NOK 52 and NOK 81 couplings:

• NOK 52: used for (O-)bundles
• NOK 81: standard firefighting coupling for 52 mm and 75 mm hoses, nozzles, distributors, etc.

The fit of the Storz wrench is optimized for these two sizes, which are used in 99% of all cases (In The Netherlands). This makes it work better, faster, and ensures a perfect connection.

Advantages of the Storzy Coupling Wrench for Fire Hoses:

✅ Lightweight design – No annoying movement in the pocket
✅ Super-strong composite – Made of glass fiber reinforced polymer
✅ Rounded edges – No more holes in firefighting suits
✅ Perfect fit – Specially designed for NOK 52 and NOK 81 couplings
✅ Stable connection – No wobbling thanks to the wide contact surface
✅ Excellent grip – Easy to use with or without gloves
✅ Heat-resistant – Made of heat-resistant polymer, won’t melt in your pocket

The Storzy fire wrench is a smart choice for every firefighter looking for a durable, safe, and perfectly fitting coupling wrench. Prevent unnecessary repair costs for firefighting gear and experience the convenience of a tool truly designed for the fire service.

The Storzy is ideal for:

• Fire departments
• Junior fire brigades
• Industrial fire brigades
• Defense forces
• Other professionals working with Storz couplings

A Sustainable Alternative to Steel

The Storzy is not only light and strong but also a sustainable choice. Thanks to the use of high-quality, glass fiber reinforced polymer, the wrench is extremely wear-resistant, heat-resistant, and dimensionally stable – even under heavy use. Unlike metal wrenches, it does not rust, requires no maintenance, and lasts a long time without deformation or breaking. Moreover, it prevents damage to firefighting suits, extending the lifespan of protective equipment. Less replacement, fewer repairs, less waste – that’s true sustainability.
