context_page_description: A hose coupling is a connector on the end of a hose to connect it with another hose or with a tap or a hose appliance, such as an irrigation sprinkler. It is usually made of steel, brass, stainless steel, aluminium or plastic.
  Due to the great variety of the designs and the number of countries in which they were created, it is difficult to trace the origin of many. Patents that cover designs similar to those below include:
  1876: HOSE-COUPLING, No.175,232.
  Coupling for hose and pipe. US 894900 A
  1915: Coupling. US 1248558 A
  1931: Coupling. US 1947593 A
context_section_description: A Storz coupling is a quarter-turn or sexless coupling, commonly used to connect to fire hydrants.  It is easy to connect, has no particular male or female end, and lugs are on the inside of the joint. This is the standard coupling on fire hoses in Denmark, Germany, Austria, Poland, Switzerland, Sweden, the Netherlands and Greece. It is also widely used in Australia. It can be manufactured by casting for general hose connection and low pressure applications, but for firefighting, it is better to use forgings to guarantee the safety and durability of the coupling.
  Storz couplings are available in several sizes, supporting hoses with an internal diameter of between 12 and 250 mm, and are specified by DIN standards 14301, 14321, 14322, and 14323 (hose couplings); DIN standards 14306, 14307, 14308, and 14309 (threaded adapters); DIN standards 14341, 14342, and 14343 (swivel reducers); and DIN standards 14310, 14311, 14312, and 14313 (caps).
  First patented: Switzerland, Patent No. 3,134, published November 26, 1890
