Storz System C Coupling with 2" Male Thread DIN 52-C, Storz Coupling, Firefighting Coupling
Storz System hose couplings are often referred to as firefighting couplings.
These are symmetrical, non-shut-off couplings.
The couplings are connected by inserting the claw 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, firefighting, refineries, agriculture, construction, shipping, military, and disaster control
Application:
- for closing couplings with 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 firmly screwed on one side with a pipe thread on a water-bearing fitting or on 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 for their protection (e.g., against the ingress of dirt into pumps) and must not be pressurized if the line cannot be relieved (risk of accident when loosening the blind cap under pressure).
