What is a Storz coupling and its benefit on the fireground?

• A. A quick-connect, symmetrical coupling that requires threading and allows slow connections
• B. A locking valve that seals automatically
• C. A threaded adapter used for gas lines
• D. A quick-connect, symmetrical coupling that requires no threading, enabling rapid connections

Answer: (D)

On the fireground, speed and reliability are essential. A Storz coupling is a quick-connect, symmetrical design where both halves are identical, so there’s no male or female end to worry about. Instead of threading, you align the lugs and give a quarter-turn to lock, forming a high-pressure seal. This threading-free, all-same-size compatibility allows hoses to connect rapidly from either end, even in poor visibility or with bulky gear. The result is faster deployment of lines, less chance of cross-threading or misalignment, and quicker water flow into the apparatus or attack line.
