Storz fire hose couplings are a type of quick-connect coupling used in the marine industry for firefighting. They are made of high-strength aluminum alloy, brass or stainless steel and feature a symmetrical design that allows for easy and reliable connection between hoses. Storz couplings are highly resistant to corrosion and wear, and can withstand high pressure and extreme temperatures. They are often used on fire hoses onboard ships and in ports, where quick and efficient response to fire emergencies is critical.
