Frequently Asked Questions
Which hose and connection systems does the Storz coupling suit?
It is a German-standard Storz quick-connect coupling with a self-sealing edge, used for hose-to-hose and hose-to-nozzle connections with clear water and foam mixture media. Hydrant outlet threads (such as BS336, NIST or KWS) need the matching adapter — the coupling itself is the quick-connect interface.
What pressure rating and sizes are available?
Working pressure is 1.6 MPa, in sizes covering 2.5" (DN50 / DN65 / DN80 / DN100 / DN150), in aluminum with optional brass or chrome plating.
Does the coupling come with barbs for hose fitting?
Yes — the Storz connection uses quick-connect with barbs for attaching to layflat hose ends, and can be supplied factory-fitted or loose depending on the order.
Can it be used with the Model 8-65 layflat fire hose?
Yes. The 2.5" size matches the Model 8-65 (65mm) hose configuration — pair it with our layflat fire hose and adjustable pistol grip nozzles for a complete line set.
