Aluminum Storz Fire Coupling (2.5" · German Standard) — Locks in One Hand, Stays Dry

A leaking hose joint buys the fire seconds. Threaded joints take two people and a wrench, and they drip at the seal while the line is under pressure.

The Storz coupling locks in one hand. A quarter turn seats the self-sealing gasket and locks the joint, no tool, no drip. Under 1.6 MPa the seam stays dry, clear water or foam, and the line is ready to throw.

Aluminum, brass or chrome, 2.5 inch (65 mm) German standard, barbed for lay-flat hose, factory pre-fitted or loose. For fire departments, marine lines, and any 65 mm line set from hydrant to nozzle.

Aluminum Storz Fire Coupling (2.5" · German Standard) — Locks in One Hand, Stays Dry — how it works

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.
