Storz couplings

Storz coupling is a quick-release, symmetrical coupling. There is thus no difference between the male and the female coupling. This coupling has a gasket for sealing, and two claws which position into each groove of the other coupling, thus locking the two couplings. A half-turn rotation clamps the couplings together. To separate (take apart) the two Storz couplings, you just need to make a half-turn in the other direction. These operations have to be carried out using a Storz spanner especially designed for this purpose.

The dimensions for Storz couplings are measurable in-between claws, these couplings being intended for a working pressure of 16 bars/225PSI.

Storz couplings are available in several diameters, DN25 to DN200.

For discharge couplings:

• A: Distance between claws: 133mm; for hose Inner diameter 110mm (Din14300)
• B: Distance between claws: 89 mm; for hose Inner diameter 75mm (Din14303)
• C52: Distance between claws: 66 mm; for hose Inner diameter 52mm (Din14302)
• C42: Distance between claws: 66 mm; for hose Inner diameter 42mm (Din14332)
• S32: Distance between claws: 66mm; for hose Inner diameter 32mm (Din14330-1)

For suction couplings:

• A: Distance between claws: 133mm; for hose Inner diameter 110mm (Din14323)
• B: Distance between claws: 89 mm; for hose Inner diameter 75mm (Din14322)
• C : Distance between claws: 66 mm; for hose Inner diameter 52mm (Din14321)
• D: Distance between claws: 31 mm; for hose Inner diameter 25mm (Din14301)
