Which couplings are connected with locks or cams rather than screw threads?

• A. Non-threaded couplings
• B. Storz couplings
• C. Threaded couplings
• D. Quick-connects

Answer: (A)

Non-threaded couplings are designed to connect using locks or cams rather than screw threads. They use locking mechanisms—like cam arms, locking collars, or interlocking lugs—to secure the connection and seal with a gasket, allowing quick, threadless connections. Storz and cam-lock styles are examples of this type, but the broad category that fits the description best is non-threaded couplings. Threaded couplings, by contrast, rely on screw threads to fasten the connection.
