STORZ Couplings are used to connect large diameter hoses to fire sprinkler systems. They are also used in road tankers, for loose bulk substances, and in the agricultural and food industries. In the construction industry, they are used in irrigation and drainage systems.
Storz couplings are manufactured from brass and stainless steel. They are available in a wide variety of sizes, such as 44, 51, 81, and 66 mm. They are also available with blank caps to protect them from dirt and debris. They can also be pressurized. They have a bayonet locking head and a collar. They are rated for 150 to 250 psi operating pressure. They are also easy to assemble and disassemble.
The Storz coupling locking head has two lugs on its swivel head. It can be used to secure any combination of fittings. It can be equipped with blanking caps and serrated hose tails. The locking head also has a maximum working pressure of 16 Bar.
Storz connections are standardized and available in a wide variety of sizes. They are most commonly used in flange connections. These are connected by bolting the flanges together with a gasket. The lugs and slots are then aligned, which means that the hooks of the opposing coupling must be inserted into the flange slot of the other coupling. The hooks then lock into place. The latches of the two couplings form a water-proof seal.
In fire departments, Storz couplings are used to connect large diameter hydrants to fire sprinkler systems. They are also connected to water hydrants used as an alternative water supply. They can also be used to feed water into building standpipes.
