Storz couplings: Features, benefits and applications

Storz couplings are a pioneering solution in industrial connection systems that promote both safety and efficiency in the process industry. With their unique design that allows quick connection and disconnection, Storz couplings help reduce downtime and improve overall productivity in complex production processes.

Storz couplings are a robust and efficient coupling system that today is a key component in both the firefighting and process industries. These couplings are especially known for their hermaphroditic design, which means that both ends are identical. This makes them incredibly versatile as they can be connected to other couplings of the same diameter without requiring specific male or female ends.

We sell Storz couplings in aluminum and stainless steel.

Storz couplings are connected using a bracket with a matching lug dimension, also known as the Ka-distance, measured in millimeters. The most common Ka-distances are 31 mm, 66 mm, 89 mm and 133 mm, but many other sizes are also available.

Our Storz coupling, swivel prevent unnecessary twisting of hoses and pipes when connecting, reducing stress on the coupling and reducing the risk of damage to the hose or pipe. Their versatile design makes them easily adaptable to different hose and pipe sizes, across various industrial applications.

Storz couplings are essential in the process industry where they promote reliability and efficiency. These couplings are designed to create tight, fast connections, making them ideal for the transportation and distribution of liquids and gases. Especially in chemical plants where safe handling is critical, Storz couplings are indispensable as they ensure there are no leaks, thus reducing the risk of dangerous spills.

In addition, they are able to withstand high pressures and temperatures, making them suitable for demanding industrial environments. In the food industry, their ability to enable quick changeovers between production lines is invaluable. This not only minimizes the risk of contamination, but also increases production capacity by saving time during changeovers. Their versatility and reliability make them a preferred choice for many companies looking to optimize their operational processes.

Choosing the right Storz coupling depends on several factors, including the specific application and the environment where the coupling will be used. It is crucial to consider the material, as couplings intended for clean environments in the food industry require corrosion-resistant materials such as AISI 316/EN 1.4401 stainless steel.

In addition, you need to ensure that the couplings' Ka-distances - the measure that defines compatibility - fit your existing systems. To meet different needs, we offer a range of both fixed and swivel couplings in aluminum and stainless steel.

As mentioned, Storz couplers are connected using a suitable bracket. If the couplings have different sizes, coupling adapters can be used to switch from one Ka-spacing to another. Our Storz coupling reducer, fixed serves as the ideal transition piece.

We offer a comprehensive range of Storz couplings and accessories to meet your industrial needs. Our experts are ready to advise you on choosing the right coupling and accessories for your specific application. We deliver high-quality products and ensure you get the right solution.

Yes, there are international standards for Storz couplings. Typical sizes range from 25 mm (1 inch) to 150 mm (6 inches) in diameter.

Storz couplings for the chemical and food industries differ primarily in material selection and hygiene requirements, where the food industry requires stainless steel and approved seals for food contact, while the chemical industry uses chemical-resistant materials. In addition, couplings for the food industry must meet strict hygiene and cleaning requirements, while the chemical industry focuses on chemical resistance and safety in explosive environments.
