What is the purpose of threaded couplings on hoses?

Threaded couplings on hoses are specifically designed to create a secure connection between different lengths of hose or between the hose and other equipment, such as nozzles and hydrants. They are commonly used on hoses that are 3 inches in diameter or smaller. This coupling method allows firefighters to connect hoses quickly and efficiently, ensuring a reliable flow of water during firefighting operations.

Threaded couplings ensure that the hoses can be easily disconnected and reconnected, which is vital for maintaining an effective water supply in the dynamic environment of firefighting. They are made from various materials, including aluminum and brass, and are not limited to a specific type of hose. While attack hoses may feature threaded couplings, they are also used on other types of hoses, enhancing their versatility.
