Storz is the main coupling system used by many countries worldwide. The Storz coupling is available in sizes from 1” to 12”, (25mm to 300mm), which makes it the only symmetrical quick coupling that offers such a large range of sizes. Advantages: you only require one coupling system, internally protected coupling lugs, a high variety of designs and materials, worldwide application in all industry sectors, easy and quick to use, and easy to handle. Depending on the pressure rating required, the Storz head, or nut, is available as a pressure forging or as a die cast piece in aluminum, brass and stainless steel. Because of the internally protected coupling lugs, the Storz coupling is protected against impact and is extremely durable. They can be easily coupled through a 120 degree rotation and can be uncoupled just as quickly.
