Storz couplings are named after the German inventor and engineer Carl August Guido Storz, who first patented the coupling design in Switzerland in 1890 and later in the US in 1893. Today, they are used primarily in the fire-fighting and process industries, in which they are used to connect industrial hoses or other devices to each other when working with gases or liquids. Storz couplings are particularly known for their ease of use, as they are quick and easy to connect and disconnect, regardless of function and application.
The Storz coupling is a hermaphrodite coupling which, instead of having a male and a female coupling, consists of two identical ends which can be connected to any other end of the same diameter. At Alfotech we sell Storz couplings in aluminium and stainless steel. Storz couplings are connected using a matching bracket with the same lug dimension, also known as the Ka distance measured in millimetres. The most common Ka-distances are 31 mm, 66 mm, 89 mm and 133 mm. However, many other sizes are also available. If the couplings have different sizes, coupling adapters can be used to go from one Ka distance to another, e.g. 89 mm to 66 mm.
Different types of Storz-couplings:
Storz couplings are manufactured according to specific standards, including DIN and ISO, depending on the application. On this basis, they are safe to use and meet all necessary safety and quality requirements. Typically used gaskets when connecting Storz couplings are made of NBR and silicone.
Storz couplings require relatively little maintenance and are easy to clean. However, to ensure optimum performance and a long lifespan, it is recommended that they are inspected regularly and cleaned as required. It is also important to use appropriate cleaning agents depending on the type of liquid or gas being transported.
If you need Storz couplings, it is important to consult a professional supplier about your specific needs and the necessary certifications. At Alfotech, we have several variants in stock and are always available for a no-obligation chat and advice on which Storz solution would best suit your operating situation. We have years of experience in finding the right model for tankers, for example. Contact us by phone +45 7020 0422 or by e-mail email@example.com.
