Storz System D Nozzle 1"AG
for 25-D coupling with 1" internal thread (not included)
Storz System hose couplings are often referred to as fire brigade couplings.
They are symmetrical, non-shut-off couplings.
The couplings are connected by inserting the lug parts into each other and twisting them against each other.
The connection fittings to be coupled are identical on the coupling side and can be connected in any way, provided they are the same size.
Field of application:
for industry, fire brigade, refineries, agriculture, construction, shipping, military, and disaster control
Application:
- for sealing couplings of the appropriate size
- Quick connection and disconnection with a 120° turn
Suction coupling:
Suction couplings are used for connecting suction hoses.
Fixed coupling:
Fixed couplings (threaded pieces in many variants) are used for connecting hoses to fittings. They are permanently screwed on one side to a pipe thread on a water-carrying fitting or a hydrant. On the other side, the usual couplings of a pressure hose or a suction hose can be connected.
Blind coupling:
Blind couplings (i.e., end caps for temporarily unused Storz connections) are used as an end on fittings to protect them (e.g., against dirt entering pumps) and must not be pressurized if the line cannot be relieved (risk of accident when releasing the blind cap under pressure).
