One of the important and fundamental elements in providing fire safety for residential, commercial and industrial buildings is the fire hose rail. Although the fireman can also use hose rail at the beginning of the fire, but the design and production of this product is for ordinary people and untrained residents of the building. At the end of each hose rail, there is a three-position nozzle, which is very important for its correct operation.

Ariacoupling or Shut-off-Nozzle is a type of three-mode aluminum nozzle that is used in the construction of hoserails. High strength at the same time being light, high resistance in hydrostatic test up to 18bar and the ability to connect to a semi-hard hose (rubber hose) 1 and 4.3 inches, are the most important features of this nozzle. The working pressure of this nozzle is 12bar and its test pressure is 18bar. . This product is designed and manufactured based on the requirements and standards of BS EN 671-1.
