Products Description
German-Type Storz Couplings
Hose Accessories - Fire Coupling
Storz couplings - also known as Storz fittings - are the symmetrical, quick-connect fire hose couplings that fire brigades and industrial safety teams across Europe rely on to connect and disconnect hoses in seconds, without tools and without regard to orientation. CA-FIRE manufactures the full DN25–DN150 range in stainless steel, brass and aluminium, built to DIN/EN norms for pressures up to 25 bar.

Overview
Built for the moment every second counts
When a hose has to go from coiled to charged in an emergency, there is no time to align threads or hunt for a wrench. The Storz coupling solves that problem by design: two identical, symmetrical half-couplings that lock together with a quarter turn, from any angle, by hand. This "genderless" connection is what makes Storz fittings the standard choice for firefighting, industrial water transfer, and mining and marine applications throughout Germany and much of the rest of Europe.
CA-FIRE produces its Storz coupling range entirely in-house, from raw billet to finished, pressure-tested fitting. Every size from the compact DN25 branch coupling up to the DN150 large-diameter suction coupling is available, manufactured in investment-cast stainless steel 316, forged brass, or cast-and-forged aluminium, and finished with NBR or FKM elastomer gaskets suited to the operating temperature range of your project.
Tool-free connection
Symmetrical halves lock with a quarter turn by hand - no threading, no orientation to check, no wrench required.
DIN / EN compliant
Dimensions and lug spacing manufactured to DIN/EN normative regulation for cross-compatibility with third-party Storz equipment.
Material flexibility
Investment-cast SS316, forged brass, or cast-and-forged aluminium - matched to your corrosion, weight and budget requirements.
Rated to 25 bar
Working pressure of 25 bar / 362 psi with a 16 bar / 232 psi test pressure, verified on every production batch.

Thread and gasket options are selected to fit the hose end, hydrant outlet or valve the coupling will mate with, and to suit the ambient and media temperature of the application - from cold-store and marine environments up to high-temperature industrial process lines.
Dimensions
Storz lug space reference
Storz sizes are identified by letter code and by "Ka" - the outer lug-to-lug span across the coupling head. Matching Ka correctly is what guarantees a Storz coupling from CA-FIRE will interlock cleanly with hydrants, branches, and hose ends already in service in the field, regardless of manufacturer.
Lug Space (Ka) by Code
| Code | Lug Space - Ka |
|---|---|
| Storz A | 133 mm |
| Storz B | 89 mm |
| Storz C | 66 mm |
| Storz D | 31 mm |
| Storz 65 | 81 mm |
| Storz 38 | 52 mm |
Not sure which code your project needs? Send us the hydrant, monitor or hose-end drawing you're matching against and our engineering team will confirm the correct Storz code, thread, and gasket combination before quoting - at no cost to you.
Finish
Anodized aluminium, your colours
Aluminium Storz couplings can be hard-anodized in custom colours for department identification, hose-diameter coding, or brand consistency across a fleet - without affecting corrosion resistance or the coupling's pressure rating. Anodizing colour, and private branding, can be specified per order.
Applications
Where CA-FIRE Storz couplings are specified
Municipal & brigade firefighting
Hydrant-to-hose and hose-to-branch connections on pumper trucks and fire engines.
Industrial fire protection
Fixed hydrant systems, hose reel cabinets and monitor feed lines in plants and warehouses.
Marine & offshore
Deck fire mains and emergency water transfer lines exposed to salt-air corrosion.
Mining & quarrying
Dewatering and dust-suppression hose runs needing fast, tool-free reconnection.
Agriculture & irrigation
Large-bore water transfer between pumps, tankers and field lines.
Rental & event water supply
Temporary hose runs that must go up and come down quickly, without matched genders.
FAQ
Q: Can CA-FIRE match a Storz code we're already using in the field?
A: Yes. Send us the hydrant, monitor, or hose-end drawing - or the coupling itself - and we'll confirm the exact Storz code, Ka lug space, thread and gasket combination before quoting, so the new couplings interlock cleanly with equipment already in service.
Q: Do you offer OEM branding and custom packaging?
A: Yes. We offer logo printing, custom anodizing colours, and custom packaging with low MOQ, and can produce to your own drawings or an approved sample under OEM/ODM terms.
Q: Can we get a sample before placing a bulk order?
A: Yes, samples are available for testing and approval. Our R&D and engineering team can also review your specification or drawing first and confirm feasibility before you commit to a sample run.
Q: What is the lead time after payment?
A: Standard lead time is 10–40 days depending on the product, material and order quantity. We'll confirm an exact production and shipping schedule once your specification and quantity are finalized.
Q: How are orders shipped, and can we visit the factory?
A: We ship by major couriers for small orders and by air or sea freight for bulk orders. You're also welcome to visit our 50,000 m² factory in Nan'an, Quanzhou - just let us know your travel dates and we'll help arrange pickup and a facility tour.
